Requires the `read:data_feed` token scope. ## OpenAPI ````yaml GET /data_feeds/{data_feed_friendly_id}/sources openapi: 3.1.0 info: title: Mangrove - API version: 1.1.0 description: > ## Filtering and sorting List endpoints that accept `filter` take one query parameter per condition, written `filter[field][comparator]=value`, for example `filter[name][contains]=North`. The comparators are `eq`, `neq`, `gt`, `geq`, `lt`, `leq` and `contains`, and `filter[field]=value` is short for `eq`. Conditions combine with AND. `contains` matches part of the value, is case-sensitive, and applies only to text fields. An unknown field or comparator, a value that doesn't fit the field's type, or a list or object as the value returns 400 with a message naming the problem. Each list operation names its filterable fields; some take only `eq`, and say so. `sort` takes a comma-separated list of fields, for example `sort=-created_at,name`. Each field sorts ascending, or descending with a `-` prefix. Unknown sort fields are ignored. Sorting by `id` orders by the record's internal ID, not its friendly ID. Each list operation names its sortable fields. servers: - url: https://app.gomangrove.com/api/v1 security: - sec0: [] paths: /data_feeds/{data_feed_friendly_id}/sources: get: tags: - Data Ingestion summary: List the data sources on a data feed description: >- Returns the sources attached to a data feed, oldest first, including each source's `config` and fetch `state`. `credentials` are never returned.
