Pass nested arrays in API Connector with Form-data

Tips
1

Here is my solution for passing nested structures via API connector with Form-data because I’ve not found this in the forum and struggled a lot.

Initial situation

Field with nested array for multiple options. In my case it was a section for ‘custom_fields’.
To create or edit the external system, I’ve to pass the field_id and the value like in the API documentation of the external system mentioned.

“custom_fields”: [
{
“field_id”: 1,
“entity_type”: “candidate”,
“field_name”: “Salutation”,
“field_type”: “dropdown”,
“value”: “”
},
{
“field_id”: 2,
“entity_type”: “candidate”,
“field_name”: “Custom summary”,
“field_type”: “longtext”,
“value”: “”
}

]

For the salutation (external field_id = 1) and internal bubble array [0].
custom_fields[0][field_id]
custom_fields[0][value]

For the summary (external field_id = 2) and internal bubble array [1].
custom_fields[1][field_id]
custom_fields[1][value]

And so on for more field to pass …

Used this because of the external system ONLY allows requests with form-data for this request.

Hope this helps.
Every hint, extension or helpful information will be highly appriciated to this topic.

Your solution is fine if your array is always the same size. If you need something dynamic, it won’t work. There’s a few solutions to help on the forum but the incremental numbering is a big issue actually in Bubble. However,there’s also plugins that will convert a JSON into url form data
