Set Up Devin V3 Credentials

Validate that DEVIN_SERVICE_USER_TOKEN and DEVIN_ORG_ID are correctly set, then verify permissions with live API calls (required org-scoped and optional enterprise-scoped).

Workflow

Step 1: Check Prerequisites

Run all prerequisite checks in a single Bash call:

printf '=== Prerequisites ===\n'
command -v curl >/dev/null 2>&1 && printf 'curl: ok\n' || printf 'curl: NOT FOUND\n'
command -v jq  >/dev/null 2>&1 && printf 'jq:   ok\n' || printf 'jq:   NOT FOUND\n'

printf '\n=== Environment ===\n'
[ -n "${DEVIN_SERVICE_USER_TOKEN:-}" ] && printf '%-28s set\n' 'DEVIN_SERVICE_USER_TOKEN:' || printf '%-28s NOT SET\n' 'DEVIN_SERVICE_USER_TOKEN:'
[ -n "${DEVIN_ORG_ID:-}" ]            && printf '%-28s set\n' 'DEVIN_ORG_ID:' || printf '%-28s NOT SET\n' 'DEVIN_ORG_ID:'

If any of the following are true, report all that apply and stop (do not continue to Step 2):

• curl not found: "curl is required. Install via your system package manager."
• jq not found: "jq is required. Install from jqlang.github.io"
• DEVIN_SERVICE_USER_TOKEN not set: show the Setup Instructions block below.
• DEVIN_ORG_ID not set: show the Setup Instructions block below.

If all pass, continue to Step 2.

Step 2: Validate Token Format

token="${DEVIN_SERVICE_USER_TOKEN:-}"

if printf '%s' "$token" | grep -qE '^apk_'; then
  printf 'ERROR: V1 API key detected (apk_ prefix).\n'
  printf 'V3 requires a service user token (cog_ prefix).\n'
  printf 'Migration:\n'
  printf '  1. Go to Enterprise Settings > Service Users\n'
  printf '  2. Create a new service user with UseDevinSessions + ViewOrgSessions + ManageOrgSessions\n'
  printf '  3. export DEVIN_SERVICE_USER_TOKEN="cog_your_new_token"\n'
  printf '  4. Remove the old DEVIN_API_TOKEN export\n'
  exit 1
fi

if ! printf '%s' "$token" | grep -qE '^cog_[a-zA-Z0-9_-]{20,128}$'; then
  printf 'ERROR: DEVIN_SERVICE_USER_TOKEN format invalid.\n'
  printf 'Expected: cog_ followed by 20-128 alphanumeric/dash/underscore characters.\n'
  printf 'Check Enterprise Settings > Service Users for the correct token.\n'
  exit 1
fi

printf '%-18s valid (cog_ prefix confirmed, length ok)\n' 'Token format:'

Never echo the token value in any output. Only describe format mismatches.

If the Bash call exits non-zero (apk_ detected or invalid cog_ format), stop here — display the error message above and do not proceed to Step 3.

Then validate DEVIN_ORG_ID:

org="${DEVIN_ORG_ID:-}"

if ! printf '%s' "$org" | grep -qE '^[a-zA-Z0-9_-]{4,64}$'; then
  printf 'ERROR: DEVIN_ORG_ID format invalid.\n'
  printf 'Expected: 4-64 alphanumeric/dash/underscore characters.\n'
  printf 'Find your Org ID at Enterprise Settings > Organizations.\n'
  exit 1
fi

printf '%-18s valid (%s)\n' 'Org ID format:' "$org"

If the Bash call exits non-zero (invalid org ID format), stop here — display the error message above and do not proceed to Step 3.

Step 3: Probe Org-Scoped Permissions

Probe the org-scoped API to check ViewOrgSessions (list) and ManageOrgSessions (message).

DEVIN_API_BASE="https://api.devin.ai/v3"
ORG_URL="${DEVIN_API_BASE}/organizations/${DEVIN_ORG_ID}"

printf '\n=== Permission Checks ===\n'
printf 'Probing ViewOrgSessions (list)...\n'

response=$(curl -s --connect-timeout 5 --max-time 10 \
  -w "\n%{http_code}" \
  -X GET "${ORG_URL}/sessions?first=1" \
  -H "Authorization: Bearer ${DEVIN_SERVICE_USER_TOKEN}")
curl_exit=$?
http_status=${response##*$'\n'}
body=${response%$'\n'*}

Outcome mapping:

• curl non-zero exit:
  • Exit 6: "Could not resolve api.devin.ai — check DNS or internet connectivity." Stop.
  • Exit 7: "Could not connect to Devin API — the API may be temporarily down." Stop.
  • Exit 28: "Request timed out — check network connectivity and try again." Stop.
  • Other: "Network error (curl exit $curl_exit)." Stop.
• HTTP 200: ViewOrgSessions confirmed. Record as PASS. Verify response uses items array (not sessions).
• HTTP 401: "Authentication failed (401). DEVIN_SERVICE_USER_TOKEN was rejected. Rotate the token at Enterprise Settings > Service Users." Stop immediately.
• HTTP 403: Record ViewOrgSessions as MISSING. Continue to collect all permission failures before reporting.
• HTTP 404: "Organization not found (404). Verify DEVIN_ORG_ID matches the ID shown at Enterprise Settings > Organizations." Stop.
• HTTP 5xx: "Devin API server error ($http_status). Try again in a few minutes." Stop.
• Other: "Unexpected HTTP status $http_status." Redact and show first 200 chars of body: printf '%s' "$body" | sed 's/\(cog\|apk\)_[a-zA-Z0-9_-]*/***REDACTED***/g' | head -c 200 Stop.

All error output must sanitize tokens: sed 's/\(cog\|apk\)_[a-zA-Z0-9_-]*/***REDACTED***/g'

Never use curl -v, --trace, or --trace-ascii — they leak auth headers.

Step 3b: Probe ManageOrgSessions

If Step 3 returned HTTP 403 (ViewOrgSessions MISSING), skip this step — ManageOrgSessions requires ViewOrgSessions as a prerequisite.

If Step 3 returned HTTP 200 (ViewOrgSessions PASS), probe ManageOrgSessions by POSTing a message to a known-invalid session ID. The API checks permissions before resource existence, so 403 means the permission is missing while 404/422 means it's present (the session doesn't exist but the permission check passed).

DEVIN_API_BASE="https://api.devin.ai/v3"
ORG_URL="${DEVIN_API_BASE}/organizations/${DEVIN_ORG_ID}"

# Probe ManageOrgSessions by sending to a dummy session ID
# Note: Devin API (FastAPI) checks RBAC before resource existence — empirically
# validated as of 2026-03. This is undocumented behavior; if probe returns
# unexpected results, the "Other" outcome treats them as UNKNOWN.
printf 'Probing ManageOrgSessions (message)...\n'
dummy_session="00000000000000000000000000000000"
response=$(jq -n --arg msg "probe" '{message: $msg}' | \
  curl -s --connect-timeout 5 --max-time 10 \
    -w "\n%{http_code}" \
    -X POST "${ORG_URL}/sessions/${dummy_session}/messages" \
    -H "Authorization: Bearer ${DEVIN_SERVICE_USER_TOKEN}" \
    -H "Content-Type: application/json" \
    -d @-)
curl_exit=$?
http_status=${response##*$'\n'}
body=${response%$'\n'*}

Outcome mapping:

• curl non-zero exit: Same as Step 3. Stop.
• HTTP 404 or 422: ManageOrgSessions confirmed (PASS). The session doesn't exist but the permission check passed.
• HTTP 401: "Authentication failed (401). Token rejected." Stop immediately.
• HTTP 403: Record ManageOrgSessions as MISSING. Continue to collect all permission failures before reporting.
• HTTP 5xx: "Devin API server error ($http_status). Try again later." Stop.
• Other: Record as UNKNOWN. Redact and show first 200 chars of body: printf '%s' "$body" | sed 's/\(cog\|apk\)_[a-zA-Z0-9_-]*/***REDACTED***/g' | head -c 200 Continue to Step 4.

Step 4: Probe ViewAccountSessions (Optional)

Make a read-only call to the enterprise sessions endpoint. This permission is optional — the plugin works without it (org-scoped messaging is preferred).

DEVIN_API_BASE="https://api.devin.ai/v3"
printf 'Probing ViewAccountSessions (enterprise list)...\n'

org_param=$(jq -rn --arg o "${DEVIN_ORG_ID}" '@uri "\($o)"')
if [ $? -ne 0 ] || [ -z "$org_param" ]; then
  printf 'ERROR: jq failed — cannot URL-encode DEVIN_ORG_ID. Ensure jq is installed.\n'
  exit 1
fi

response=$(curl -s --connect-timeout 5 --max-time 10 \
  -w "\n%{http_code}" \
  -X GET "${DEVIN_API_BASE}/enterprise/sessions?org_ids=${org_param}&first=1" \
  -H "Authorization: Bearer ${DEVIN_SERVICE_USER_TOKEN}")
curl_exit=$?
http_status=${response##*$'\n'}
body=${response%$'\n'*}

Outcome mapping:

• curl non-zero exit: Same as Step 3. Stop.
• HTTP 200: Enterprise endpoint accessible (ViewAccountSessions confirmed). Record as PASS.
• HTTP 401: "Authentication failed (401). Token rejected." Stop immediately.
• HTTP 403: Record ViewAccountSessions as MISSING. Continue to Step 5. This is not a critical failure — org-scoped messaging works without it.
• HTTP 404: "Enterprise sessions endpoint not found (404)." Stop.
• HTTP 5xx: "Devin API server error ($http_status). Try again later." Stop.
• Other: "Unexpected HTTP status $http_status." Redact body. Stop.

Step 5: Report Results

Collect results from Steps 3, 3b, and 4 and display a unified status table:

Devin V3 Setup Check
====================

Prerequisites
  curl                         OK
  jq                           OK

Credentials
  DEVIN_SERVICE_USER_TOKEN     OK  (cog_ format confirmed, token not echoed)
  DEVIN_ORG_ID                 OK  ([DEVIN_ORG_ID value])

Permissions (required — org-scoped)
  ViewOrgSessions (list)       [OK | MISSING]
  ManageOrgSessions (message)  [OK | MISSING | UNKNOWN]

Permissions (optional — enterprise-scoped)
  ViewAccountSessions          [OK | MISSING]

Overall: [PASS | PARTIAL | FAIL]

Note: UseDevinSessions (create) cannot be probed non-destructively. If the list endpoint (ViewOrgSessions) passes, create is typically also granted. If session creation later fails with 403, the user should verify this permission.

If ViewOrgSessions is MISSING, display:

Required permission ViewOrgSessions is missing.

To fix:
  1. Go to Enterprise Settings > Service Users in the Devin web app
  2. Select your service user
  3. Grant these org-scoped permissions:
       UseDevinSessions    — Create sessions
       ViewOrgSessions     — List and get sessions
       ManageOrgSessions   — Send messages, terminate, archive
  4. Re-run /devin:setup to verify

If ViewOrgSessions is OK but ManageOrgSessions is MISSING, display:

Overall: PARTIAL PASS

ManageOrgSessions is missing — session messaging, cancellation, and archival
will fail with 403. Session listing and creation work normally.

A PR comment fallback is available: review feedback can be posted as GitHub PR
comments with @devin prefix instead of using the API message endpoint.

To fix:
  1. Go to Enterprise Settings > Service Users in the Devin web app
  2. Select your service user
  3. Grant: ManageOrgSessions — Send messages, terminate, archive
  4. Re-run /devin:setup to verify

If ViewOrgSessions is OK but ViewAccountSessions is MISSING, display:

Overall: PARTIAL PASS

ViewAccountSessions is missing — enterprise-scope session listing unavailable.
Org-scoped messaging (the primary path) will still work as normal.

Note: ManageAccountSessions (enterprise-scope messaging) cannot be probed
non-destructively. If enterprise messaging fails with 403 later, grant it at
Enterprise Settings > Service Users.

To enable enterprise-scope features:
  1. Go to Enterprise Settings > Service Users
  2. Grant: ViewAccountSessions — Enterprise-scope session listing
  3. Grant: ManageAccountSessions — Enterprise-scope messaging (optional)
  4. Re-run /devin:setup to verify

If all checks pass, display:

All checks passed. The yellow-devin plugin is ready to use.

Next steps:
  /devin:delegate — Delegate a task to Devin
  /devin:status   — List recent sessions
  /devin:wiki     — Query repository documentation

Then ask via AskUserQuestion: "What would you like to do next?" with options: /devin:delegate, /devin:status, /devin:wiki, Done.

Setup Instructions

Show this block when DEVIN_SERVICE_USER_TOKEN or DEVIN_ORG_ID is not set:

DEVIN_SERVICE_USER_TOKEN and/or DEVIN_ORG_ID are not set.

To configure:
  1. Create a service user:
       Enterprise Settings > Service Users > Create new user
       Required permissions:
         - UseDevinSessions
         - ViewOrgSessions
         - ManageOrgSessions
       Optional permissions:
         - ViewAccountSessions
         - ManageAccountSessions
       Token format: cog_<...>

  2. Find your Org ID:
       Enterprise Settings > Organizations

  3. Add to your shell profile (~/.zshrc or ~/.bashrc):
       export DEVIN_SERVICE_USER_TOKEN="cog_your_token_here"
       export DEVIN_ORG_ID="your-org-id"

  4. Reload your shell profile:
       source ~/.zshrc   (or ~/.bashrc)

  5. Restart Claude Code and re-run /devin:setup

Never commit tokens to version control.
