[] Square bracket problem

I need to send keys to HelloSign API in the format signer[0][name] but I cant seem to enter square brackets in the key field in the back end workflow

Can anybody point a nooby in the right direction?

edit: When I try to type the square bracket in the key field, the cusror jumps to the end of the input text


Can you link us to the relevant API documentation so we can have a look?

Yes thank you.

Here is the relevant page for my call which is POST /signature_request/send

I have the call set up in the bubble API plugin, initialized and working. So I am trying to set up the back end workflow with only the 3 required parameters.

The call works in Postman also and the only issue I have is I cant type a square bracket in the parameter key.


Hi thanks for your offer but I got it to work today.


Hi @thedon
Can you share how you got this to work? Iā€™m having the same issue.

Hi Paul. If I remember correctly, setting the body type to Form-data rather than JSON solved the problem for me
