How do I pull Many-Date requests?

[Aregets]

I have 2 endpoints that most of my data comes from that uses "/{Start Date}/{End Date}"

For this I have made a parameter for the {Start Date} to begin where our data starts, and a parameter for {End Date} being "Today()" and just filter the data as needed.

I now added an Endpoint that uses "/{Business Date}" that only pulls single dates.

While trying to figure this out, I have also realized that some of my "/{Start Date}/{End Date}" endpoints request returns no DATE to help reference.

Question 1: Is there a way to pull a request for each "/{Business Day}"? (like a loop?)

Question 2: How would I handle receiving the "/{Start Date}/{End Date}" endpoint that has no DATE reference? Could I also pull each day with solution from Question 1 and conditionally add a DATE column myself?

Hi @Aregets ,

Thank you for reaching out to Microsoft Fabric.

1. Using a list accumulation approach in Power Query within Power BI. This technique essentially functions like a loop, generating a list of business days and then making API calls for each date.

2.  The issue of receiving the /{Start Date}/{End Date} endpoint with no date reference can be resolved by setting up incremental refresh in Power BI. This approach ensures efficient data updates.

An official Microsoft document has been attached, providing detailed information on this topic. Please review it when possible for further insights.

Question 1: You can use List.Accumulate.

Question 2: I don't understand what you mean. If there is no data between [Start Date] and [End Date] there's nothing to pull. If  there is, ensure your filter checks for dates between as well as the actual dates ege: data >=[Start Date] and data <=[End Date].
