An industry-standard authorization framework allowing applications to securely access APIs without sharing user passwords.
Why OAuth Matters
Connecting a messaging platform to a CRM or spreadsheet used to mean handing over a username and password. OAuth replaces that: the user approves a specific, limited access on the other service's own consent screen, and the connecting app never sees their password.
How OAuth Works
The app redirects the user to the provider (Google, HubSpot, Salesforce and so on) to log in and approve a defined set of permissions, called scopes. The provider returns a short-lived access token, plus a refresh token to renew it, and the app calls the API with the token. The user can revoke access at any time without changing their password.
How SMPPCenter Uses This
SMPPCenter's Google Sheets, HubSpot, Salesforce and Zoho connector plugins connect through OAuth, and resellers can configure their own OAuth credentials in White Label so the consent screen their customers see carries the reseller's branding.
