API Method DirectAddressValidate
Contents |
Description
The following code samples describe the processes involved in "validating" a Direct address and discuss what happens behind the scenes with domain-level address validation and address-level validation.
Behind the Scenes
When a call is made to /DirectAddressValidate, a search is performed for a current, non-revoked certificate for the target Direct address. There two types of certificates to search for:
Address-level Certificates
For a recipient Direct address of DrTom@DrTomsPractice.MyEHRDirect.com, the first certificate search looks for a certificates issued for the recipient address: DrTom@DrTomsPractice.MyEHRDirect.com. If the immediate issuer (or any of the parent issuers) of the certificate is trusted and the certificate has not been revoked, then /DirectAddressValidate will return true. This does not mean that the address itself is guaranteed to exist or that messages sent to it will be picked up by the intended recipient - only that a valid, non-revoked certificate signed by a trusted agency can be found for the address
Domain-level Certificates
For a recipient Direct address of DrBob@DrBobsPractice.OtherEHRDirect.com, if no trusted, non-revoked certificate can be found for the address, the next certificate search will be performed on the domain of the intended recipient: DrBobsPractice.OtherEHRDirect.com. A Domain-level certificate is used for all users in a given domain. The same certificate will be used to sign messages from DrBob@DrBobsPractice.OtherEHRDirect.com as will be used to sign messages from NurseRatchett@DrBobsPractice.OtherEHRDirect.com. Since there aren't any user-specific (aka Address-specific) certificates available to be searched, the most precise anyone can be about determining if the recipient Direct-address is valid is to confirm the existence of a trusted, non-revoked certificate for the domain. Again, this does not mean that the address itself is guaranteed to exist or that messages sent to it will be picked up by the intended recipient - only that a valid, non-revoked certificate signed by a trusted agency can be found for the domain.
Prerequisites
1 This API call requires Vendor-level credentials. The credentials should be populated into the applicationId and applicationPassword fields of the auth block:
{
...
"auth": {
"applicationId": "vendorId",
"applicationPassword": "vendorPassword",
"accountId": "",
"userId": ""
}
}
