In the strictest of definitions, this is true. However, it supports Airtable with far better agility and more so the case than Airtable can claim it supports itself.
Ideally, perhaps, but it seems this is off the table for this user. Power Automate (formerly Microsoft Flow) is very powerful and it’s not irrational that your IT team has enforced this policy. It is extremely secure, reliable, integrated deeply into all that is Microsoft, and it provides a mature approach to integration architectures that scale and require no additional fees. The total cost of ownership for automated services is prepaid and fixed - even at massive scale.
Power Automate supports inbound webhooks and Airtable supports HTTP(s) API integrations using automated script actions or manually clicked buttons. Airtable Script Blocks and Custom Blocks can also make calls to Microsoft Power Automate webhooks.
Power Automate also supports outbound webhooks, but alas, Airtable doesn’t support inbound webhooks. To overcome this, you need a webhook proxy or you need to use the Airtable API (in Power Automate) to mimic a webhook action with Airtable.
All said, Power Automate integrates just dandy with Airtable in both directions and I’ve created solutions that utilize all of these approaches.
This is achieved through an Airtable script action.
Power Automate must be configured to listen for a script action from Airtable and then proceed to create the Jira ticket (which it is fully capable of doing). Since your IT team insists on using Power Automate, you should ask them to help you create that part of the process. Once they set up the webhook, then com back to this thread and ask for more clarity concerning the script action.
