How to get historical Bid and Ask Price using RDP/API account

Hi,

I'm trying to figure out what the best scope would be to grab historical Bid and Ask prices when using the RDP/API account?

Below is what I have but I'm running into issues. Could you just confirm if this is correct or not?

--data-urlencode 'grant_type=password'
--data-urlencode 'username= 'XXXXX'
--data-urlencode 'scope= 'trapi.data.historical-pricing.events.read'
--data-urlencode 'client_id= 'XXXXX'
--data-urlencode 'password= 'XXXXX'
--data-urlencode 'takeExclusiveSignOnControl=true'

I get this error when trying to get the token to work

{'error': {'id': '8c45e309-f6ef-433e-987e-329cc84ec98d', 'code': 'insufficient_scope', 'message': 'access denied. Scopes required to access the resource: [trapi.data.historical-pricing.events.read]. Missing scopes: [trapi.data.historical-pricing.events.read]', 'status': 'Forbidden'}}

Many thanks!

Thank you for reaching out to us.

The error indicates that the account doesn't have permission to access the historical pricing service due to missing the required in the account.

Please contact your LSEG account team or sales team directly to verify the account's permission.

Hello @Settlements

You can use the /historical-pricing/v1/views/interday-summaries/ endpoint to get historical data. You can find more detail on the RDP API Playground page.

There are much more services under the /historical-pricing endpoint that might suite your need. If you need more information about what you can query, you can click on the "Reference" tab on the service page.

Once you got an access token, you should be able to query the Historical Pricing HTTP GET service with the following command:

curl --location "https://api.refinitiv.com/data/historical-pricing/v1/views/interday-summaries/EUR=?interval=P1D&count=20&fields=BID%2CASK" --header "Authorization: Bearer <access token>"

Note: Your RDP account must have a permission to access the Historical Pricing service as suggest @Jirapongse
