Hello @efe.sen

You can find more information about RDP Authentication rate limitation and other detail from the following resources:

• Limitations and Guidelines for the RDP Authentication Service article.
• RDP API - Tutorials: All About Token
• RDP API - Tutorials: Authorization in Python

The Python example code is available on the RDP API - Download page. It saves an access token to a file and then the data-request example gets an access token from that file.

Hello @efe.sen

I can answer some questions only. Please see my answers below.

Question 1: Company Fundamentals: Batch Retrieval: Is there a way to retrieve fundamentals data as a batch?

Answer: I checked the https://apidocs.refinitiv.com/Apps/ApiDocs page, the Reference section shows that it supports multiple universes requests as follows:

I did a quick test on the API Playground page, and it works fine.

Question 2: Company Fundamentals: Parallel Requests: Is there a way to parallelize the requests for fundamental data retrieval?

Answer: You can use Python threading or asyncio feature to send an HTTP request to RDP in concurrent.

• Async IO in Python: A Complete Walkthrough

We do not have the exact example code that the client needs, but there a lot of example code over internet such as:

• Concurrent HTTP requests in Python
• Fastest parallel requests in Python
• Python Requests: Make Concurrent Requests
• Parallel web requests in Python
• How to call multiple API requests concurrently in Python

Question 3: Historical Pricing: Macroeconomic Indicators: Is there a way to retrieve macroeconomic indicators (RIC codes ending with =ECIX) and company pricing history as a batch?

Answer: I am not sure about the Macroeconomic Indicators, but the Historical Pricing API supports the batch subscription via an HTTP Post message. I strongly suggest you try it on the API Playground page (https://apidocs.refinitiv.com/Apps)

Question 4: Historical Pricing: Macroeconomic Indicators: Parallel Requests: Is there a way to parallelize the requests for historical pricing data retrieval?

Answer: About the parallelize the requests for historical pricing data, you can use Python threading or asyncio feature to send an HTTP request to RDP in concurrent.

• Async IO in Python: A Complete Walkthrough

We do not have the exact example code that the client needs, but there a lot of example code over internet such as:

• Concurrent HTTP requests in Python
• Fastest parallel requests in Python
• Python Requests: Make Concurrent Requests
• Parallel web requests in Python
• How to call multiple API requests concurrently in Python

Please note that the number of requests should not exceed the limit mentioned on the Reference page of the historical pricing endpoint.

About the rest of questions, I strongly suggest you check the Reference page of that API endpoint on the API Playground page for more detail.

Hi, thanks for your answers. Here is my update:

About Answer 1: So, at max I can retrieve 5 RIC codes at a time from company-fundamentals.

About Answer 2: I checked the reference page of company-fundamentals, but could not see any limitation regarding to the throttling, I was wondering if there is maximum limit of concurrent sessions.
Also, is it possible to use the same access token with parallel sessions? Let's say throttle rate is 5 (most of the time I saw that number in the different API references), do I need to get access for each individual sessions, or get token once and use it in concurrent sessions?

About Answer 3: I have also tried to use /data/historical-pricing/v1/views/interday-summaries endpoint with multiple macroeconomic indicators, but got the following error:

Answer 4: Probably going to use the same solution (if my assumptions are correct) as answer 2.


I am still wondering if it is possible to retrieve data with currency (for both fundamental and macroeconomic indicators), also which endpoint that I can utilize to check next earnings & release date for both fundamental and macroeconomic indicators.

Thanks in advance!

Hello @efe.sen

### company-fundamentals ###

I have checked with the Online Solution team; the team confirms that the endpoint supports maximum 5 RIC code per request.

### The API Limit ###

There is a API generic throttling limits information on the RDP API General Guidelines document as follows.

I cannot find the limit information on the /data/company-fundamentals/v1/financial-statements/global/balance-sheet endpoint reference page, but there is a limit information on the /data/historical-pricing/v1/views/interday-summaries/{universe} endpoint reference page as shown below.

### is it possible to use the same access token with parallel sessions? ###

If the parallel requests are made by the same application/session, an application can use the same access token with a concurrent HTTP request messages to RDP.

However, if you have multiple applications, it is advisable to use multiple Machine-IDs to avoid the session stolen issue when refresh an access token.

Hello @efe.sen

Please see my answers (continue).

### /data/historical-pricing/v1/views/interday-summaries with Economic Indicator RIC ###

I re-checked the endpoint reference page on the https://apidocs.refinitiv.com/Apps/ApiDoc website. It says the endpoint supports Economic data request via the HTTP GET operation only. That means an application can request a single Economic RIC per request.

I did a quick test, but I do not have a permission to request this kind of RIC.

### About the Currency and Date information ###

The questions are involved both RDP technical and content side which I am not have a knowledge. I strongly suggest you contact the RDP support team directly. You can contact the team via https://myaccount.lseg.com/en/productsupport website.

I hope this information helps.
