FAQ

Frequently Asked Questions.

Q: I'm interested in using Manheim APIs. How should I get started?

A: Please contact your Manheim Account Representative to determine which APIs would meet your needs.

Q: My company uses a firewall and I need to whitelist the IP address for one or more Manheim APIs. What are the IP addresses that I should allow?

A: We cannot provide a specific address or set of addresses for whitelisting. Manheim APIs are hosted in the AWS Cloud, so the IP address for each API changes frequently.

Q: I would like to talk with someone about the application that I'm building to see if it's a good fit?

A: Please contact your Manheim Account Representative to set up a consultation call.

Q: Is there a limit on how frequently I can call Manheim APIs?

A: Manheim sets limits for API usage at two levels. We limit the number of calls that can be made per minute, and we limit the total number of calls that can be made per day. If you have a specific need, we will be happy to work with you to determine the best limit settings for your application.

Q: I'm not getting the response I expect. Where should I look for more information?

A: Each Manheim API endpoint provides error messages in the response. The body of each error message should detail specifics about an error. The documentation for each page may also contain additional error information in the "Common Return Codes" sections.

Q: I'd like to interact with an API without having to write client code. Is this possible?

A: Yes. For Manheim REST APIs, all requests and responses occur over HTTPS. cURL is a great tool for interacting with an API over HTTPS to verify your code. To query your API with cURL, you must first obtain an access token ...

curl -X POST \
https://integration1.api.manheim.com/oauth2/token.oauth2 \
-H 'authorization: Basic <client_ID:client_secret in base-64 encoded string>' \
-H 'content-type: application/x-www-form-urlencoded' \
-d grant_type=client_credentials

... and then use that token to request information from the API just as you would in your own software:

curl -H 'Authorization: Bearer <Token from above here>' https://integration1.api.manheim.com/valuations/vin/WDBRF52H76F783280
