Hi,

Are there any updates to help stream answers from HTTP String responses? It'd be game changer.

Categories:

Hello @BMAUK , Currently, Power Automate does not support true streaming of HTTP responses. All HTTP responses are handled as complete payloads, meaning the flow waits for the full response before continuing. However, there are workarounds and evolving capabilities that hint at future improvements.

What Power Automate Supports Today

• The “Send an HTTP request” action in both cloud and desktop flows retrieves the entire response at once.
• You can parse large responses using JSON, XML, or text string manipulation, but streaming (i.e., processing data as it arrives) is not natively supported.
• This limitation affects scenarios like:
⁠◦ Long-running API calls
⁠◦ Real-time chat or AI responses
⁠◦ Large file downloads or paginated data

Resources & Updates

• Microsoft Learn – HTTP Actions in Power Automate 🔗

• SPGuides – REST API in Power Automate

• Stack Overflow – HTTP Request Workarounds

Microsoft has not yet announced native support for streaming HTTP responses in Power Automate, but with the rise of AI integrations and real-time data needs, it’s a feature many developers are hoping for.
