123FormBuilder API – API Responses

At some point, while using our API, you may fail to access the data from your 123FormBuilder account. It’s best that you understand from the very beginning the cause of these errors. Therefore, here is a complete list of all the API responses you’d receive, with explanations attached.

In XML and JSON, the API error messages appear as tags (<errorMessage>), respectively names/keys (message).

table.api-messages {border-collapse:collapse;}
table.api-messages td {padding:5px 10px !important; width:350px; border:1px solid #ccc;}
td.pinktext {color:#c80042;}

    1. Hello Pavan!

      I apologize for the late reply. From what I see, your problem is linked to a 405 status code error, which can be fixed by adding a trailing slash, as explained in this article. If this is not the case, may I suggest waiting for one of my colleagues from customer support to reply to your previous email with a proper solution.

      For assistance, don’t hesitate to contact our Support Team at support@123formbuilder.com or via our contact form.
