When WordPress lead uploads move to the Data Manager API, rejected rows should be grouped into clear fix categories: missing click IDs, invalid conversion action, consent denied, bad timestamp, malformed user data, duplicate lead ID, or temporary API failure.
Use this for Elementor, Gravity Forms, Contact Form 7, WPForms, CRM, and webhook pipelines that upload qualified leads or enhanced conversions for leads to Google Ads.
Quick answer
Data Manager API Error Codes for WordPress Lead Uploads should be handled with a narrow evidence-first workflow: capture error detail, group causes, assign owners, then verify the result before making broader changes.
What to check first
- Store each upload result with lead ID, form ID, CRM stage, conversion action, timestamp, consent state, and error detail.
- Group errors into permanent data issues, temporary API issues, policy or consent issues, and mapping issues.
- Make permanent errors visible to marketing operations before retries waste quota.
- Retry only temporary failures and keep event IDs stable across retry attempts.
- Run a weekly rejected-row report that names the field owner and fix.
Diagnostic table
Use this table to keep the work practical. It connects the symptom to evidence and a verification step.
| Action | Evidence to collect | How to verify |
|---|
| Capture error detail | Store each upload result with lead ID, form ID, CRM stage, conversion action, timestamp, consent state, and error detail. | Every rejected row has a readable error group and owner. |
| Group causes | Group errors into permanent data issues, temporary API issues, policy or consent issues, and mapping issues. | Permanent errors are not retried until the source field is fixed. |
| Assign owners | Make permanent errors visible to marketing operations before retries waste quota. | Temporary errors keep the same event or lead ID across retries. |
| Retry temporary rows | Retry only temporary failures and keep event IDs stable across retry attempts. | Marketing can see accepted, rejected, and pending counts without server access. |
Why this usually happens
- A server log shows a raw API error but does not name the CRM field that caused it.
- Retry queues can repeatedly send rows that will never pass because consent or mapping is wrong.
- Marketing cannot fix a hidden field problem if the rejection stays inside engineering logs.
- One bad row can hide many accepted rows when partial failure handling is weak.
Field notes
- Use real lead IDs in internal reports, but avoid exposing personal data in shared docs.
- Normalize error categories across Google Ads and CRM names so non-engineers can act.
Useful command or data shape
Adapt paths, IDs, and privacy handling to the site before running commands or storing data on production.
upload_error_row:
lead_id: gf-20260707-1882
form_id: demo_request
conversion_action: qualified_lead
consent_state: granted
click_id_present: false
error_group: missing_click_id
owner: form_tracking
retry_policy: do_not_retry_until_fixed
Safe fix order
Do the work in a sequence that makes each result easy to prove. Stop if a step produces new evidence that changes the incident scope.
- Capture error detail
- Group causes
- Assign owners
- Retry temporary rows
- Report weekly
What to tell the client or owner
Tell marketing which rejection categories are costing qualified lead uploads and who owns each fix.
Production verification checklist
- Every rejected row has a readable error group and owner.
- Permanent errors are not retried until the source field is fixed.
- Temporary errors keep the same event or lead ID across retries.
- Marketing can see accepted, rejected, and pending counts without server access.
Mistakes to avoid
- Do not judge the fix by one browser or the homepage only.
- Do not delete evidence before recording usernames, file paths, timestamps, and response headers.
- Do not add a cache, security, or tracking plugin while the original problem is still unclear.
- Do not leave test users, temporary debug logs, or broad API keys active after verification.
When HandL WP should help
Bring in help when this affects leads, checkout, search visibility, malware risk, paid media reporting, or a client production site. HandL WP can trace the issue through WordPress, hosting, cache, tracking, and Search Console, then verify the workflow after the technical fix.
If this is active on a production site, fix WordPress lead upload errors.

Specific Data Manager validation runbooks
For status retrieval failures, follow the INVALID_REQUEST_ID retention test. For rejected oversized fields, use the FIELD_VALUE_TOO_LONG field-policy guide so identifiers and consent values are not silently truncated.
New Data Manager boundary-error runbooks
For newly documented validation reasons, use the FIELD_VALUE_TOO_SHORT boundary test instead of padding or inventing values. When a repeated list is oversized, follow the TOO_MANY_ELEMENTS batch-splitting policy to preserve request IDs, deduplication, rate limits, and final record reconciliation.
New Data Manager validation and location runbooks
For newly documented error reasons, use the TOO_FEW_ELEMENTS boundary test to find where filtering emptied a required collection. When automatic insight location fails, follow the BASELINE_LOCATION_AUTO_DETECTION_FAILED workflow to separate source normalization, account mapping, eligibility, and fallback behavior.
New Data Manager API dimension and variable diagnostics
For v1.7 insight coverage, use the INSIGHTS_MISSING_FOR_DIMENSION fix to narrow the request and return a typed unavailable state. For destination mappings, run the CUSTOM_VARIABLE_NOT_FOUND mapping test before replaying queued events.
WooCommerce coupon code normalization
For purchase or refund rows rejected with INVALID_COUPON_CODE, use the WooCommerce coupon event fix to normalize multiple, deleted, empty, encoded, and edited coupon codes while preserving transaction and event IDs.
Destination and user-data error routing
For source and destination incompatibility, use the EVENT_SOURCE_AND_DESTINATION_MISMATCH fix. If the identifier represents the wrong resource type, use the DESTINATION_ACCOUNT_TYPE_MISMATCH account matrix. Field-level rejects belong in the INVALID_CUSTOM_VARIABLE_VALUE workflow, while partner-sourced identifiers require the THIRD_PARTY_USER_DATA_NOT_ALLOWED audit before any approved replay.
Google Analytics identifier and property errors
If an event contains mutually exclusive web and app identifiers, use the Data Manager API client ID and app instance ID conflict fix. If the Analytics destination is a reporting property that cannot accept the operation, use the Google Analytics subproperty and roll-up fix to resolve the eligible source property.
Store-sales merchant identifier errors
When request status reports an invalid store-sales account value, use the Data Manager API INVALID_MERCHANT_ID fix to trace the field path, normalize only approved digits, repair the authoritative store map, and replay rejected events without duplicating accepted ones.
