Slack Workflow App Development

Job ID: 30976412

Budget: $250 – $750 USD

We want to:
1. Create a Slack Workflow that prompts a user to enter some information in a form [DONE - see image]
2. POST that data to a Webhook API call to a foreign system (ProcessMaker) that has a very simple POST body syntax.
3. The foreign system (ProcessMaker) uses OAuth and requires a bearer token on the POST.
4. Retrieves the response from the POST, formats the data and posts back to the Slack channel.

We know we need to create a "Slack App" for this and that's the part where we are mainly struggling and need help. We expect that there will be some light JavaScript development required but we're not 100% sure.
