--- title: REST API Collector slug: changelog/rest-api-collector docTags: createdAt: 2025-12-23T08:32:18.728Z --- ## v4.5.1 Released on 25/08/2026 ### Bug fixes - Fixed `StopTimeShift` collector setting adjusting both start and stop time instead of only stop time. ## v4.5.0 Released on 10/08/2026 ### Bug fixes - Fixed measurements being validated before the collector settings are merged into them. A measurement that inherits its URL, query parameters, body or method from the collector is no longer rejected with ` or value is missing from Config`. - Fixed `` and `` not being found in nested POST bodies. The templates are now accepted anywhere they are also substituted, including in nested objects, in lists of objects and in lists of strings. - Fixed `` and `` not being replaced in a POST body list of strings, such as `{"times": ["", ""]}`. - Fixed an empty collector `Method` being rejected. It defaults to `GET`, as the setting has always documented. ### Changes - Configuration errors now name every setting that needs attention in a single message, instead of always reporting the time templates as missing. A missing URL and an unsupported method are reported as such. - `URL` is now a required collector setting. A collector without one never started, so this reports the problem while configuring instead of on startup. Measurements can still override the URL. ## v4.4.1 Released on 16/07/2026 ### Changes - A request is again rejected when neither the URL, the query parameters nor the body contain `` and ``. The check was lost in an earlier refactor. - Updated the base collector to v3.5.3 ## v4.4.0 Released on 22/04/2026 ### Changes - Added `StopTimeShift` collector setting to shift the stop time of each live query by a configurable number of seconds (negative values shift into the future). ## v4.3.1 ### Bug fixes - Fixed small mistake in trace log message ### Changes - Added http response body in error log when request fails ## v4.3.0 ### Changes - [Updated the base collector to v3.5.2](docId\:dJs1GFlKyD1m31dXQH5CU) ## v4.2.1 Released on 14/11/2025 ### Bug fixes - Fixed collector not respecting PROXY environment variables ## v4.2.0 Released on 24/10/2025 ### Changes - Add setting to forcefully shut down the collector after a certain amount of time ## v4.1.0 Released on 08/10/2025 ### Changes - Added support for client credentials grant type. ## v4.0.6 Released on 30/09/2025 ### Changes - Removed pattern constraint on request body. ## v4.0.5 Released on 10/09/2025 ### Bug fixes - Fixed issue where deleted measurements were still being processed by the parser ## v4.0.4 Released on 04/06/2025 ### Bug fixes - Fixed measurements being added before collector was initialized ## v4.0.3 Released on 21/05/2025 ### Changes - [Bump to base collector v3.1.1](docId\:dJs1GFlKyD1m31dXQH5CU) - [Bump to parsers v5.0.0](docId\:itL5rCuMLTCsAkzjO54yt) ## v4.0.2 Released on 03/04/2025 ### Changes - Bump to parsers v4.1.0 ## v4.0.1 Released on 29/01/2025 ### Changes - Disabled streaming until a data loss fix is implemented - [Updated the base collector to v2.7.3](docId\:dJs1GFlKyD1m31dXQH5CU) ## v4.0.0 Released on 08/01/2025 ### Changes - Bump to parsers v4.0.2 ## v3.0.0 Released on 21/08/2024. ### Changes - Bump to base collector v2.4.8 and to parsers v3.0.0 - Switch to unrequired collector settings: URL and Method - Pass collector context to parser for a graceful collector shutdown - Only parse received responses when pausing/closing collector instead of finishing all open requests ## v2.1.1 ### Changes - Added support for performance monitoring with Pyroscope ### Bug fixes - Restored windows 7 compatibility - [Updated base collector to v2.4.8](docId\:dJs1GFlKyD1m31dXQH5CU) ## v2.1.0 ### Bug fixes - Fixed waitgroup bug ### Changes - Added CollectionType setting - Implemented monitored data collection ## v2.0.4 ### Bug fixes - Fixed waitgroup bug ## v2.0.3 ### Bug fixes - Fixed ability to override requests per measurement - Fixed wrong status code for point on failed request ## v2.0.2 ### Changes - Include parser name in collector type and binary name ## v2.0.1 ### Bug fixes - Fixed memory leak ## v1.0.4 ### Bug fixes - Removed naming conflict in settings ### Changes - Allow looking back further than the current interval, overlapping with the previous interval - Allow configuring time zone for query timestamps ## v1.0.3 ### Bug fixes - Fixed initialization of tags map ### Changes - [Updated the base collector to v1.2.16](docId\:dJs1GFlKyD1m31dXQH5CU) ## v1.0.2 ### Bug fixes - Fixed StopTimeHistoric not being optional ### Changes - Adding body to POST request - Supported content types for body: application/json, application.xml, application/x-www-form-urlencoded - Possibility to retrieve status and other tags from the json response - [Updated the base collector to v1.2.15](docId\:dJs1GFlKyD1m31dXQH5CU) ## v1.0.1 ### Bug fixes - Fixed measurement overrides influencing collector settings ### Changes - Allow reading historic data - Added configurable timeouts for API calls ## v1.0.0 Beta release for the REST API collector ### Features - Adding query parameters to GET request - Parsing for json response
