}Create a hosted pick-and-connect link for a client
Returns a LedgerSync-hosted URL you email to an end-user (a member).
They open it, search for their own bank, pick it, and connect it — no
institution_id needed up front. This is the v3 replacement for the
old “add/lite” widget for integrators who don’t want to build their
own bank picker.
Call this with your normal API key. Optionally pass a redirect_url
(which must be on your environment’s allowlist) to send the member
back to your app after they finish connecting.

}Authorizations
Pass your secret key in the Authorization header as a Bearer
token: Authorization: Bearer sk_test_... (sandbox) or
Bearer sk_live_... (production).
Keys are created in the developer portal and the plaintext secret is shown exactly once at creation. Treat them like passwords — never embed them in mobile apps or front-end code.
Path Parameters
Body
Where to send the member after a successful connect. Must exactly match one of your allowlisted redirect URLs for this environment. Omit to end on the connect widget's own success screen.
