General

After creating the transaction using the API, why is the recipient not receiving an email from AngelList with an invitation link to start onboarding?

AngelList only sends out an email invitation to the recipient if you create a transaction using the UI on AngelList's website.

AngelList currently does not support sending an email if you use the API to create a transaction and redirect the recipient to AngelList for onboarding using the JWT flow.

If you want an email to be sent, you will have to implement it on your server.

JWT

After using the JWT url, why am I stuck in a loading page and not redirected to the appropriate transaction page?

This usually means there's an error with the authorization of an operation on AngelList using the JWT. Open the browser developer console to see the error and use the Error troubleshooting guide for the JWT flow to debug each error.

Is there any max limit for the expiration that we can set on the JWT?

Not currently.

Is there a way to retrieve the transmitToken for a previously created transaction?

transmitToken is part of the transactionRecipient object, which is created and linked to the transaction object when you create the transaction using the mutation. We don't expose the transmitToken as part of the transactionRecipient query from the public API. You have to create another transaction if you have lost the transmitToken.
