# Square OAuth application secret (`square_oauth_secret`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Application secret of a Square developer application, which the application uses to exchange OAuth authorization codes for access tokens. It starts with sq0csp- followed by 43 characters. It is a different credential from a Square access token. Examples are left out because GitHub push protection rejects token-shaped values, even constructed ones.
