API connection with Holded ERP

Thank you very much Artemus.

I tried it but there is something more to do. I did:

- Blank query

- Erase let / in schema

- paste directly 

Web.Contents("https://api.holded.com/api/invoicing/v1/contacts", [Headers=[Accept="application/json"], ApiKeyName="Key"])

- Replace "key" with my key "exxxxxxxx..."

- Power BI send a message to "edit credentials"

- I put my API key at "API Web"

- Power BI show a message asking that it couldn't authenticate the credentials.

I don't know what I did wrong.

Maybe It is related with:  (https://developers.holded.com/reference/api-key)

- All API requests must be made over HTTPS and Content-type as application/json.

- Include your Api Key in the Header key : . I also tested:

    * 1:

= Web.Contents("https://api.holded.com/api/invoicing/v1/contacts", [Headers=[Accept="application/json"],
ApiKeyName="key: exxxxxxxxxxxx"])

   * 2:

= Web.Contents("https://api.holded.com/api/invoicing/v1/contacts", [Headers=[Accept="application/json"],
ApiKeyName="key:exxxxxxxxxxxx"])
