Add new connector: Basis Platform API#1930

Requested connector: Basis Platform API (not the existing “Basis DSP” connector, which targets the Standalone DSP API — a separate product; Basis has confirmed Platform customers cannot use Standalone DSP credentials).

• Docs: https://api.basis.net/docs/
• Base URL: https://api.basis.net/v1 (sandbox available at https://api-sandbox.basis.net/v1)
• Auth: OAuth2 at https://auth.basis.net — supports client credentials flow (client_id + client_secret + audience=https://api.basis.net), authorization code, and refresh token grants
• Reporting endpoints: GET /v1/stats/{scope} with scopes line_item, daily_by_line_item, and daily (impressions, clicks, video completions, eCPM/eCPC/eCPV); dimension metadata via /v1/campaigns, /v1/campaigns/{id}/line_items, /v1/clients, /v1/brands, /v1/creatives, /v1/conversions
• Rate limits: 75,000 requests/hour per API user; token generation capped at 10/hour, 25/day (relevant for refresh scheduling)

What data do you need from it? (required)

Line item and campaign delivery stats: spend, impressions, clicks, conversions, video completions, and performance metrics (eCPM, eCPC, eCPV), ideally at daily-by-line-item granularity via GET /v1/stats/{scope}. Plus the related metadata endpoints for joining names to IDs: /v1/campaigns, /v1/campaigns/{id}/line_items, /v1/clients, /v1/brands, /v1/creatives, and /v1/conversions.

Anything else we should know? (optional — but worth filling in, this is where the critical context goes)

This is a different product from your existing Basis DSP connector, which targets the Standalone DSP API — Basis has confirmed that Basis Platform customers like us cannot use that connector. The Platform API uses OAuth2 at https://auth.basis.net (client credentials flow supported: client_id + client_secret + audience=https://api.basis.net). Note the token quota: 10 token generations/hour, 25/day, so tokens should be cached/reused rather than generated per request. Overall rate limit is 75,000 requests/hour. A sandbox is available at https://api-sandbox.basis.net/v1. We have API credentials pending from Basis and can help test once they’re issued.
