Hi Carlos, >From what I understand, you are having trouble setting up the OAuth and access your clients account. Is that correct? If so, you can refer to the guide to setup the API access on behalf of your clients (web-flow) <https://github.com/googleads/googleads-java-lib/wiki/API-access-on-behalf-of-your-clients-(web-flow)>. Once you have the OAuth setup properly, you should be able to access the client's account via the API. If the client is looking for a means to add you as a user on the account, they could refer to this guide <https://support.google.com/adwords/answer/6372672?hl=en&co=ADWORDS.IsAWNCustomer=false> to do that via web interface.
You can use ManagedCustomerService.MutateLink <https://developers.google.com/adwords/api/docs/reference/v201710/ManagedCustomerService#mutateLink> to manage the link between accounts. This <https://developers.google.com/adwords/api/docs/guides/accounts-overview#managedcustomerservice> guide describes various scenarios with code snippets. Could you describe the issue that you are facing?
