Big Picture: Im trying to accomplish a process to automatically link records between tables.
The use case is automating a process where when a user updates their membership in an external system, airtable creates a new membership record and links it to a user account in our airtable database. Basically our CRM's membership data doesnt talk to AirTable. So Im using automations to export the data an ingest it into airtable. Once its ingested, the membership data needs to be linked with a user record in airtable.
The steps I think need to be accomplished.
1. In table A, we Create a record with a {user account number} from a database not linked to airtable.
2. In table B, I want to take the that {user account number} from Table A and match it to a record in Table B.
3. Update a linked record field in Table B with the matched record from step 2.
Im struggling with step 3 in particular. Both the external database, and the airtable user accounts table have the common "known" {user account number}. I've seen this question in various forms, but haven't seen any solutions that seems relevant to our use case. Based on what I've read in the forums, I need to use javascript. I had a look at Make, but that seems more complicated than getting a script written.
TIA
