Hey everyone, hoping for some collective wisdom here. I’m in a bit of a bind with HeyGen’s API and it’s bringing back some painful CRM migration flashbacks. You all know me—I’ve probably moved more customer data between Salesforce, HubSpot, and Zoho than most people have hot dinners, and I’ve hit my fair share of rate limit walls. But this one’s got my current automation workflow completely bottlenecked.
Here’s my setup: I’m using HeyGen’s API to personalize short video clips for new leads that come into our system. The workflow is solid—trigger from our CRM, feed data to HeyGen, get the video URL back, attach it to a follow-up sequence. The problem is the sheer volume. We’re processing several hundred leads a day during campaigns, and we keep slamming into the 60 requests per minute rate limit. The workflow just… stops. Then I’ve got a backlog, missed SLAs, and a very annoyed RevOps team.
It feels a lot like when I tried to batch-update 50,000 records in Salesforce via the API and got throttled into oblivion. The difference is, with those big CRMs, you can sometimes negotiate limits or buy add-on capacity. I’m not sure what the playbook is here.
* **Current Fix Attempts:** I’ve built a queuing system with exponential backoff, which helps, but it just delays the inevitable during peak hours. It also makes the whole process slower than we designed it to be.
* **The Real Pain Point:** It’s the *hard cut-off*. When you hit the limit, the errors come back, and everything halts until the minute rolls over. There’s no graceful degradation.
* **My Questions for the Community:**
* Has anyone successfully negotiated higher API limits with HeyGen? If so, what was the process and did it involve a different pricing tier?
* What are your architectural workarounds? Are you spreading requests across multiple API keys (if that’s even allowed) or pre-generating a library of videos for common use cases?
* Am I just using this API for something it wasn’t designed for? The marketing makes the personalization at scale seem possible, but the current limits suggest a more sporadic, one-off usage.
I love the output from HeyGen, truly. The videos are fantastic. But this bottleneck is making me look at the whole stack sideways again. I’d rather not have to build a complex proxy layer or switch tools—I’ve had enough migration drama for one lifetime! Any insights or war stories would be hugely appreciated.
Ah, the old rate limit wall. That 60 per minute feels so reasonable until you're staring at a queue of a few hundred leads. I've been down this exact road with the Salesforce Bulk API, and it's the same pain. Your point about the playbook is spot on - with smaller SaaS tools, you often can't just buy your way out of it like you can with the enterprise giants.
I'm really curious what your *Current Fix Attempts* are. Did you try implementing a basic token bucket or leaky queue algorithm in your script? I tried that once, but then found that my batch jobs were taking so long they'd spill over into peak CRM sync times, which created a whole new mess.
Have you looked at whether HeyGen's API returns any headers about your current limit status? Sometimes they'll give you an `X-RateLimit-Remaining` count, which lets you be a bit smarter than just a static sleep timer. You could dynamically adjust your request pacing based on that.

That header check is a good first move, but vendor implementation is wildly inconsistent. I've seen APIs where `X-RateLimit-Remaining` is accurate and others where it's just decorative, lagging behind by several requests. Always verify by actually hitting the limit and checking the response code timing.
Even with a dynamic throttle, you're still stuck with that 60/min ceiling, which is the real bottleneck. The real fun begins when your job queue backs up and you have to decide between delaying new leads or building a priority system. That's when the simple script turns into a distributed state management problem.
No SLA, no problem.
