Your team already records calls. The recordings pile up in a phone system, a meeting tool, or a call platform. Then someone has to listen back, write the summary, pull the action items, and paste it all into a CRM. Usually that someone is busy, so it does not happen.
Today we are closing that gap. Neural Summary now has a REST API and signed webhooks. You can push a recording in from any system you already run, and get the summary, the action items, and any Lens output you ask for back, automatically. It is available on the Enterprise plan.
What you can do with it
The API does two simple things. It takes audio in, and it sends results out.
You send a recording with optional context: the caller's name, email, phone, and your own reference ID. Neural Summary transcribes it, writes the summary, and generates whatever Lens outputs you requested, like a follow-up email, an action list, or CRM notes. When it finishes, we send a signed webhook to your endpoint. From there the result goes wherever you want it.
No one opens the app. No one copies and pastes. The conversation becomes a finished deliverable on its own.
A concrete example
Say every sales call gets recorded by your phone system. You want a drafted follow-up email waiting in the rep's inbox before they have walked back to their desk.
With Zapier, Make, or n8n, that is a few steps and no code:
- 1Your call platform delivers the recording to your automation tool.
- 2It sends the audio to Neural Summary and asks for the follow-up email Lens.
- 3Neural Summary processes the call and fires a webhook when it is done.
- 4A second flow catches that webhook and creates a Gmail draft, addressed to the caller, with the follow-up email already written.
The rep reviews a draft instead of writing one from scratch. That is the difference between a follow-up that goes out the same day and one that slips to next week.
What you get back
You are not limited to a transcript. Every recording can come back with any of our Lens outputs attached: a follow-up email, a sales email, an owners-and-dates action list, formal minutes, CRM notes, a deal qualification, a backlog, and more. You choose which ones per upload. The summary is always included.
Where to start
Everything you need is in the developer documentation: authentication, the four endpoints, the full webhook payload, signature verification, rate limits, and the Zapier, Make, and n8n recipe in full.
To get a key, open Settings then Integrations in the app, on the Enterprise plan, and create one. It is shown once. Then send your first recording.
Frequently asked questions
Which plan includes the API?
The integrations API and webhooks are available on the Enterprise plan. The key inherits your plan's monthly hours and file-size limits, and integration uploads count against the same quota as uploads in the app.
Do I need to write code?
No. Zapier, Make, and n8n all have a generic HTTP action that calls our endpoints and a catch-hook trigger that receives our webhooks. You can build the whole flow without writing a webhook handler. If you do want to handle webhooks yourself, the payload is signed with an HMAC in the same format Stripe uses, and we show example verification code in the docs.
How do I know a webhook really came from Neural Summary?
Every webhook is signed. We send an HMAC signature header that you verify with your webhook's secret, and we include a timestamp so you can reject anything older than five minutes. The developer docs include ready-to-use verification code.
What happens if my endpoint is down?
We retry. A failed delivery is attempted up to five times with exponential backoff, and every delivery shows up in Settings with a one-click replay if you need to send it again after fixing your side.
