I’m running a Make.com scenario to create a new Invoice associated with a Client. I’ve stripped it down to just the required Client ID that I’m passing in, and I’m still getting: [500] Internal Server Error.
I’m able to do other API queries like updating a Client and creating new Clients; it’s just the Create an Invoice action that’s returning the server error.
Any thoughts?
UPDATE: I’m getting the 500 server error using both the built-in Make module “Create an Invoice” as well as doing a straight API call to the https://invoicing.co/api/v1/invoices endpoint.
Sorry, I’m not too familiar with curl, I’m not sure how to do that.
I’ve added the X-Requested-With header as you suggested, and I still get the 500 error. I also added the Accept header like the documentation shows, also with no change.
I tried the Create an Invoice module, and I’m getting the same 500 server error with that. However, I am able to use other InvoiceNinja modules, so it seems my authentication and the other functions are working fine.
