Connect Wells Fargo to Hypamoon
Possible, with help from Wells Fargo. The API is documented, but you cannot just create a key: access goes through Wells Fargo first.
PossibleThe check
Three questions about the API of Wells Fargo, answered from its own docs.
- Public API docs
- Yes. The Wells Fargo Developer Portal publishes API references for account balance, ACH, wire and instant payments, plus guides for sandbox, validation and production. Read the docs
- A key you create yourself
- No. You can sign up and test in the sandbox, but production needs a company ID assigned during onboarding, a service agreement and mutual TLS certificates set up with Gateway support. developer.wellsfargo.com
- Versions or a changelog
- Yes. APIs carry a version in their path, such as ACH Payments v2. developer.wellsfargo.com
- How it signs in
- OAuth 2.0 access tokens plus mutual TLS certificates in validation and production, and a gateway company ID from onboarding.
- Webhooks
- Yes. It can tell your app when something changes. developer.wellsfargo.com
- Hosting
- Cloud
- Condition
- Production needs onboarding by Wells Fargo Gateway and a service agreement. Wells Fargo also lists pre-built integrations with partner systems.
What you can build
Pull balances and payment status of your Wells Fargo accounts into your own finance dashboard, and prepare ACH or wire payments for approval.
Your chat writes it as a Hypamoon adapter from the docs above. Reading starts after you click Allow in the portal, and every write waits for your approval, one call at a time. How adapters work
Good to know
- Wells Fargo signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Wells Fargo takes more work: ask your chat to check this first.
- Wells Fargo Gateway APIs are for commercial customers. Pre-built integrations give access to account data inside existing systems without development.
Try it in your chat
First get access from Wells Fargo. Then fill in what to read and write, and send it.

Tool not listed? Ask the chat to check its API.
The same three checks work for any software. Your chat reads the vendor's own docs and tells you what it found.
Check if [software] has an open API that a Hypamoon adapter can use: public API docs, a key or token I can create myself without asking the vendor, and versions or a changelog. Link the pages you used.
Fill in the name of your software. Checking needs no connection to Hypamoon.

Connect your chat once, then ask it to build the adapter.
