when agent tried to update the CRM, the API returned 403 and the write failed mid-run
Fixes an agent whose CRM update fails mid-run with a 403 by diagnosing whether permissions, record access, or a changed profile revoked the write. Use when reads work but writes return forbidden. Not for a 403 present from the integration's first day.
TL;DR
A 403 that starts mid-run or mid-rollout is a permission story: the integration user's profile changed, field-level security tightened, or the run reached records owned outside its sharing rules. Capture which object, field, and record the 403 names, compare against the integration user's current permissions, and restore the minimum access the job actually needs.
when agent tried to update the CRM, the API returned 403 and the write failed mid-runUse this when
- CRM reads succeed while updates return 403
- Failures may affect only some records or fields
- An admin change, profile update, or sharing recalculation happened recently
Not for this skill when
- The integration user was deactivated entirely (which usually fails reads too)
- The 403 comes from an IP allowlist after a network change
Steps
- Capture a failing request in full: object, fields, record id, and the API's error detail. Verify: the forbidden target is specified exactly
- Test the same write with an admin-scoped read of the integration user's permissions. Verify: the missing permission (object, field, or record sharing) is identified
- Check recent admin changes: profiles, permission sets, sharing rules, and field security. Verify: the change that revoked access is found or ruled out
- Restore minimum-necessary access via a permission set, not by making the user an admin. Verify: the failing writes succeed in a retest on the same records
- Add a permission smoke test (one harmless write to a test record) at run start. Verify: future revocations fail the run immediately with a clear message

Why it happens
403s are precise if you read them: the API knows which permission on which field failed. The common waste is treating them as generic auth trouble and rotating credentials, when the actual event was an admin quietly tightening a profile the integration depended on.
Edge cases / pitfalls
- Sharing rules can make a record invisible to write while list views still show it. Test on the exact failing record, not a convenient one.
- Permission restorations should be reviewed with the admin who tightened them; sometimes the tightening was a security decision the job must design around.
- Smoke-test writes need a dedicated test record so they never touch customer data.
