Getting access and using the Developer Portal
How to request API access, sign up to the Developer Portal, create Client Applications and manage your team.
What it is
Access to the Remitian Public API starts with a request to support. Once approved, your team signs up to the Developer Portal, the self-service hub where you create credentials and manage firms, webhooks, security settings and team members.
When you need it
- You are starting a new integration and do not have credentials yet.
- You need to rotate a credential, invite a teammate, or change which firms an application can reach.
How it works
- Request access. Email support@remitian.com with your company name, primary use case for the API, expected integration timeline and technical contact details. Support typically replies within 1 to 2 business days.
- Sign up. You receive an email invitation to the Developer Portal. During onboarding you also receive your External Integration ID, the unique identifier for your system.
- Create a Client Application. Each application generates its own Client ID, Client Secret and API Key. You can create several, for example one per environment or per product. Credentials are copied from the portal and are never sent by email.
- Invite your team. Editors invite members by email and assign a role.
- Grant firm access. In the Firms section, choose which Client Applications can reach which firms created through the API.

Common questions
I lost the Client Secret. Can support send it again?
No. The secret is shown only once. An Editor regenerates it in the Client Applications section, which invalidates the old value immediately, so update your systems right away.
Why can't my application see a firm?
Check the Firms section. Each Client Application only reaches the firms it has been granted.
A teammate cannot change settings. Why?
They likely have the Read-Only role. An Editor can change their role in Team Management.
Do we need support for routine changes?
No. After sign-up, credentials, team, firm access, webhooks and the IP allowlist are all self-service.
