Frequently Asked Questions

Do I need code to set this up

No code is required. Use the visual workflow builder to connect triggers and actions and configure field mappings. You can manage permissions and scopes from the admin console. For advanced control you can export logs and monitor performance. If you need enterprise scale, reach out for dedicated support.

Yes you can map custom donor and charity fields. The integration supports field mapping and data validation rules. You can upsert records to keep data in sync across GHL and the charity website. For complex schemas use nested mappings to maintain data integrity.

Common endpoints include get_charities, get_charity_website, upsert_donor and update_campaign. You may also use create_lead and get_donor_by_email for prospect and contact workflows. The exact set depends on your use case and the endpoints enabled in your plan.

Errors are logged with clear details and retry logic. Retries use exponential backoff to avoid thrashing. Set up alerts and monitoring so you can respond quickly to persistent issues. Validate data before sending to reduce common failures.

API call limits vary by plan. If you exceed limits consider batching requests or scheduling polling windows. For high volume campaigns you can request higher quotas and implement queueing to smooth traffic.

Security follows best practices with HTTPS, OAuth tokens and least privilege permissions. Use separate API keys for each app and monitor access with audit logs. Regularly rotate credentials and apply strict scopes.

API documentation is in your developer portal and in the app docs. Look for endpoints like get_charities and upsert_donor. If you need help, contact support or your account manager for guidance and code samples.
