Deep debugging techniques for complex Adobe API issues that resist standard troubleshooting: IMS token problems, Firefly async job failures, PDF Services edge cases, and network-layer diagnostics.
Prerequisites
Access to production logs and metrics
curl with verbose mode for HTTP debugging
Understanding of OAuth 2.0 token flows
Network capture tools (tcpdump, openssl s_client)
Instructions
Technique 1: IMS Token Introspection
When auth issues occur, decode the access token to check claims:
# Adobe IMS tokens are JWTs — decode the payload (middle segment)
TOKEN=$(curl -s -X POST 'https://ims-na1.adobelogin.com/ims/token/v3' \
-d "client_id=${ADOBE_CLIENT_ID}&client_secret=${ADOBE_CLIENT_SECRET}&grant_type=client_credentials&scope=${ADOBE_SCOPES}" | jq -r '.access_token')
# Decode JWT payload (base64url-decode the middle segment)echo"$TOKEN" | cut -d. -f2 | tr'_-''/+' | base64 -d 2>/dev/null | python3 -m json.tool
# Look for:# - "exp": expiration timestamp (is it expired?)# - "iss": should be "ims-na1.adobelogin.com"# - "as": scopes granted (do they match what you requested?)# - "client_id": verify it matches your ADOBE_CLIENT_ID
Technique 2: Verbose HTTP Request Tracing
# Full HTTP trace against Firefly API
curl -v -X POST 'https://firefly-api.adobe.io/v3/images/generate' \
-H "Authorization: Bearer ${TOKEN}" \
-H "x-api-key: ${ADOBE_CLIENT_ID}" \
-H "Content-Type: application/json" \
-d 2>&1 | firefly-debug.log
