New plugin: SchemaField Mapper for Bubble AI/API response mapping

Plugin builders
1

I kept seeing the same Bubble problem: the API or AI step succeeds, the JSON technically exists, but the next workflow step still cannot use the values cleanly.

I built SchemaField Mapper to handle that narrow pain.

What it does:

  • takes JSON text you already received
  • extracts the paths you care about
  • enforces required fields
  • returns clear errors when the shape is wrong
  • keeps the result usable inside Bubble workflows

Good fit for:

  • OpenAI / Anthropic / API Connector responses
  • nested JSON objects
  • webhook payload inspection
  • backend workflow return data that needs predictable fields

Not a fit for:

  • calling the model or API for you
  • writing to the database automatically
  • repairing totally broken output by magic

If anyone is stuck on Bubble response mapping pain, I am happy to compare the use case against the current plugin scope.

Quick update because Bubble has now released native JSON parsing in the API Connector, which is a good thing.

If your API Connector response now exposes the fields cleanly, use that first.

SchemaField Mapper is aimed at the remaining handoff cases:

  • JSON/text you already have inside a workflow
  • required path checks before the next step writes data
  • fallback values
  • backend return-data or plugin-response cases where the value reaches Bubble but stays awkward to use
  • clear missing-field/type errors instead of silent bad output
