Actions are restricted for live experiments, to just modifying dates and the title & description ## OpenAPI ````yaml /openapi.json put /v1/tag/{uid}/experiment/{id} openapi: 3.0.1 info: title: CI Public API description: >- # Introduction Welcome to the Content Ignite API. A central place for all Content Ignite functionality. This API enforces a separation between function and form, meaning anything you can do in our platforms can be replicated in your own bespoke solution. # Authentication Authentication is handled via JWTs. You can retrieve your unique JSON Web Token from the settings page in the platform, which needs to be passed in with every request. To do this, simple include it in an Authorization header with the "Bearer" key word. Please contact support for help getting started. # Error Codes This is a fully RESTful API, so prepare for a number of different HTTP status codes. There is also a standard "success" field returned for each request. This boolean value can provide a first check against a response. # Rate limit We reserve the right to block requests if we deem a client to be abusing the API. version: 1.0.0 servers: - url: https://api.tagdeliver.com description: Production security: - BearerAuth: [] tags: - name: Reporting - name: Reporting/Revenue Reports - name: Reporting/Experiment Reporting - name: Reporting/Campaign Reports - name: Reporting/Health Check - name: Reporting/Ads.txt - name: Reporting/Utility - name: Reporting/Insights Hub - name: Reporting/Insights Hub/SSP Insights - name: Reporting/Insights Hub/Core Web Vitals - name: Reporting/Insights Hub/Ads.txt Insights - name: Reporting/Insights Hub/Live Insights - name: Reporting/Insights Hub/Metrics - name: Reporting/Insights Hub/Diagnostics - name: Reporting/Insights Hub/Revenue Insights - name: Reporting/Insights Hub/Revenue Analytics - name: Reporting/Insights Hub/Demand Mix - name: Reporting/Insights Hub/Benchmarking - name: Organisation - name: Organisation/Organisation Meta - name: Organisation/Pricing - name: Ad Stack - name: Ad Stack/Integration - name: Publisher - name: Publisher/Publisher Stack - name: Publisher/Publisher Tag - name: Publisher/Publisher Meta - name: Publisher/Experiment - name: Publisher/Config (Ad unit) - name: Publisher/App Placement - name: Billing - name: Billing/Invoice - name: '[IN PROGRESS] Integration' - name: '[TODO] User' - name: '[TODO] User/Account' - name: public paths: /v1/tag/{uid}/experiment/{id}: put: tags: - Publisher/Experiment - public summary: /tag/:uid/experiment/:id description: >- Updates an existing config.
