Mirth connect (Need to add API CALL in existing channel, Based on API response need to add conditions in Step)

I am looking for a Mirth Connect expert to add an API call in an existing channel. The API to be used is specified by me and the output format is expected to be JSON. There is no authentication required for this API. Based on the API response, the ideal candidate should be able to add conditions in the step. The skills required for this project include Mirth Connect, API integration, and experience with JSON data. The project should be completed within a tight timeline, so the ideal candidate should be able to work efficiently and deliver quality work within the stipulated time.
