Hello Piwik pro Community, Is there a way to create multiple apps using only one http request ? if so how many ? are there any limitations ? Thank you for your support ---

Hi @nisrine, you can set up one app with one API call. When it comes to the limits - there is a limit of 10 apps for Core account. Tymek ---

Thank you for your reply . Speaking of limits; I have another question regarding custom dimensions: On piwikpro official documentation about core version Vs entreprise version there is no mention to the limits of NUMBER of custom dimenonsion allowed in each application … should I assume it’s unlimited ? if not could you provide the exacte limitation ? also is there a limit of number of custom dimension per Http request for creating cds? ---

HI @nisrine In general there is only few limits in Core accounts that you won’t have in Enterprise plan. Answering your question - you can have up to 200 Custom dimensions session-wise and up to 200 event-wise per an app. Please remember that you can’t delete any Custom Dimension. For more details see the article: [Create a custom dimension | Piwik PRO help center](https://help.piwik.pro/support/reports/custom-dimension/) When it comes to creating CD through an API call - you won’t be able to create multiple CDs in a single call. Just to be sure you’re fully equipped with the documentation - please find the article in our Developers portal: > **[Object management API](https://developers.piwik.pro/en/latest/custom_reports/object_management_api/object_management_api.html#tag/Custom-Dimensions/paths/~1api~1analytics~1v1~1manage~1custom-dimensions~1/post)** Tymek ---

Thank you 🙂 To make sure I fully understand , giving that I can create only a single custom dimension per API Call , if I need to create 10 custom dimensions in 90 piwik pro apps , i have to make 900 API calls right ? Is there any API calls quota i should be aware of ? ---

Hi @nisrine, @spujade we will handle up to 150 requests in a 10s window from one IP address, but please also consider that querying for an app with more than 120 requests per minute will exceed the limit. Tymek ---
