Connecting a form to a CRM is easy to demo and easy to get wrong in production. The demo covers the happy path. Production covers double submissions, CRM outages, unknown routing values, interrupted responses and credentials that expire. A brief that covers those cases before code starts saves most of the rework.
Start with definitions, not endpoints
Define what received, saved and assigned mean. A visitor message that says "message sent" should match the system state. If the CRM must confirm the record, say so. If the request is stored durably and processed later, the confirmation should describe receipt, and the team needs a way to find requests that stay unprocessed.
Map fields by business meaning. A person, a company and an enquiry are different records. An existing contact with a new enquiry needs a new activity or lead, not an overwritten message. Routing fields need allowed values and a controlled fallback for unknown values, not free text matching for an important assignment.
Design for the uncertain outcomes
The hard cases are worth naming in the brief. A submission identifier helps stop duplicate deals and tasks from double clicks and retries, but a duplicate delivery is not the same as a new enquiry from the same person. Using only an email address as a permanent suppression rule can discard a legitimate second request.
Also test the case where the CRM saved the record but the website did not receive the response. Retrying the whole flow without reconciliation can repeat actions. The right result is one preserved enquiry, with the agreed contact relationship, task and notification.
For errors, list each failure point, what the visitor sees, whether the request is preserved, whether retry is safe, and who is notified by name. Keep credentials server side, with only the permissions the integration needs, never in website JavaScript or a public repository. Use test and production webhook URLs correctly, and confirm the deployed site points to the published workflow, not a temporary listener.
An acceptance matrix covering new and existing contacts, missing and empty fields, unknown values, duplicates and failures turns this brief into a test plan. That is the difference between an integration that works in a demo and one that works when a real lead depends on it.
