Trouble syncing my website content workflow with Asana

Hi everyone, I run a small restaurant-focused website that publishes menu updates, reviews, and promotional content — mostly around Texas Roadhouse and similar restaurant chains. I’ve been using Asana to manage my content creation and publishing workflow for a few months now, and it’s been great for keeping track of articles, SEO updates, and scheduling posts. However, lately I’ve been facing an annoying issue where my website’s task automation setup isn’t syncing properly with Asana.

The problem started after I set up an automation between my CMS and Asana using a third-party integration tool (Zapier). The workflow is supposed to automatically create a new Asana task whenever a new draft post is added to the “Menu Updates” category on my website. This was working perfectly for a while, but now the automation either stops triggering altogether or creates incomplete tasks without titles, due dates, or assignees. I’ve checked the logs in Zapier, and it says the webhook is being received, but Asana responds with a 400 bad request error.

What’s strange is that manual task creation via the Asana API works fine when I test it through Postman, so it doesn’t seem like an authentication or API key issue. I even regenerated the personal access token and reconnected the integration, but nothing changed. It’s as if the payload structure from my website suddenly stopped matching what Asana expects. I tried validating the JSON data, and it looks fine — fields like name, projects, and assignee are all included.

Another issue I’ve run into is that my Asana project custom fields (like “Content Type” and “Publish Date”) aren’t updating automatically anymore. I added these fields so my editors can track which articles are scheduled or still pending review, but they remain empty even when my automation passes those values. I double-checked the field GIDs using the Asana API Explorer, and they’re correct. It seems like the integration is skipping them during task creation for some reason.

I also noticed that some of the automation failures correlate with high activity on my website — like when multiple editors upload drafts simultaneously. Could there be a rate-limiting issue on Asana’s API that blocks certain requests during busy periods? The error logs occasionally mention “429 Too Many Requests,” so I’m wondering if that’s part of the problem. If so, I might need to add retry logic or batch updates differently.

Has anyone else experienced broken or unreliable task automation between a website CMS and Asana? What’s the best way to debug or stabilize the sync — should I rely on Asana’s native rules instead of a third-party tool, or is there a better way to handle API rate limits? Any advice would be hugely appreciated since my editorial team depends on Asana for coordinating all our restaurant-related content, and these sync issues are really slowing down our workflow. Soryy for the long post!

When you replay the failed zap, it still fails? Do you have a screenshot of the payload?

You should be able to debug each run in Zapier and see the payload, same as above: can you share a screenshot of one failed update?

I believe you should be able to trust Zapier. I know I do :stuck_out_tongue:

Thanks for the quick response! Yes, when I replay the failed Zap, it still fails with the same 400 bad request error from Asana. I checked the task creation step in Zapier’s history, and the payload looks fine — all the key fields like name, projects, and assignee are being sent correctly. I’ll grab a screenshot of one of the failed runs and share it here shortly so you can take a look.

It’s good to know that Zapier itself should be reliable — I was starting to wonder if the issue might be on Asana’s side or something related to the payload format changes. What’s odd is that manual requests through Postman with the same JSON still work perfectly. I’m thinking maybe the problem appears when multiple Zaps trigger at once (like when several new “Menu Update” posts go live on my restaurant site, which covers chains like Texas Roadhouse).

I’ll upload the payload screenshot shortly — hopefully that helps narrow down where things are breaking. Thanks again for taking the time to help me troubleshoot this!
