This is the **default shared quota** — it is shared with every other endpoint that has no dedicated limit, so requests across those endpoints all draw from the same budget. --- Replaces the application's `clientSecret` and returns the new one. Only the application's admin (the caller's GCID must be in `adminGcids`) can rotate. Non-admins receive `404 Not Found` (opaque authorization). **The current secret is not required** - ownership is proven by the access token and the application's `adminGcids`, not by presenting the old secret, which may have been leaked; a leaked secret is the usual reason to rotate. **The previous secret stops working immediately** - there is no overlap window, so anything still using it fails as soon as this call returns. The new secret is returned **only in this response** (one-time reveal) and can never be read again, only replaced. Nothing else about the application changes. An application created moments earlier may briefly answer `404` while it propagates; retry. ## OpenAPI ````yaml /api-reference/openapi.json post /api/v1/sso/applications/{clientId}/client-secret openapi: 3.0.1 info: title: eToro Api version: v1.352.0 description: >- eToro’s public API provides access to real-time financial data, trading insights, and account management features, allowing developers to integrate eToro’s services into their applications. With access to market prices, historical data, and social trading information, the API empowers users to enhance their trading strategies. Designed for security and scalability, the eToro API ensures smooth and reliable integration for a variety of financial applications. For more details on integrating with eToro's public WebSocket service, please refer to the dedicated [WebSocket documentation](./websocket/websocket-doc.html). ## Authentication Every request must be authenticated with exactly one of two options: an OAuth 2.0 access token (`Authorization: Bearer `), or the non-interactive credential pair (`x-api-key` + `x-user-key` headers). The two options are mutually exclusive — a request carrying both is rejected. Each operation lists the OAuth scopes that grant access as alternative security requirements: a bearer token needs only ONE of them, and the same permissions govern the credential pair. servers: - url: https://public-api.etoro.com description: eToro Public API security: - apiKeyAuth: [] userKeyAuth: [] - oauth2: [] tags: - name: Agent Portfolios - name: Social Feeds - name: Balances - name: Clubs - name: Watchlists - name: Top Assets - name: App Data - name: Market Data - name: Identity - name: Cash Accounts - name: Transfer - name: Notifications - name: PI Data - name: PortfolioSearch - name: Price Alerts - name: SSO - Applications - name: SSO - Scopes - name: Sub-Accounts - eToro Trading - name: Sub-Accounts - name: Trading - Demo - name: Trading - Real - name: Users Info - name: Rankings - name: User Stats - name: Copy Trading - name: Copy Trading - Demo paths: /api/v1/sso/applications/{clientId}/client-secret: post: tags: - SSO - Applications summary: Replace OAuth client secret description: >- **Rate limit:** 60 requests per 60 seconds.
