Hi, I'm trying to connect my TikTok leads to a Salesforce Custom object through Zapier, but I get the following errors. 


Failed to create a custom object in Salesforce (Legacy)

We're getting an error for the field (insert field here, if possible). This usually happens when the value we're using in the "Custom value" isn't being accepted by Salesforce. In most cases, we want to map an ID field there, instead of what is mapped there now.

Your Zap is likely to be missing a required field, or a field value wasn't in a recognized format. For example, if a field in your action step is expecting an email address, but the value given is a name, the app may return a 400 error.

This is the only field where I think the problem might be, but I have no available options

Hi @Bobo 


It seems you are using Salesforce old integration, this is why it says Salesforce (Legacy). Use the most recent integration instead. (You probably had an older zap that used the Legacy action)

@Bobo hows it coming along over there? Were you able to switch over to the current Salesforce integration? Let us know either way, and we’re happy to keep helping you along.
