Create table record via API that includes a record link

I have two tables that are joined via a Linked Record field (Table A → Table B in a 1:1 relationship). Through REST, I would like to create a new record in Table A that include the reference to an existing record in Table B. I’ve tried something like this {“EfuYKrneFcwKzcuqG_link_left_column”: “001”} in the body of the REST call which are the field ID and the record ID respectively. But I get an internal server error. What is the correct way to create the relationship via the REST API?

hello @Lance, welcome to the Tulip Community!! it would be great if you can introduce yourself here: Welcome to the Community, let's meet!.

the only thing you need to add to the request are square brackets around the ID of the linked field. even if it’s a 1:1 relationship in the linked field, the API endpoint is expecting an array. something like this should work:

{
"ID": {{Record ID}},
"EfuYKrneFcwKzcuqG_link_left_column": ["001"]
}

here’s an example:


let me know if this helps and if you have further questions!! thanks for posting.

Outstanding. Thanks for the quick response. I actually stumbled upon this just before seeing the email and was going to go update the post. Much appreciated!

it would be interesting to see how you’re using the Table API, feel free to post in Show and tell - Tulip Community if you’d like!!
