Data driven API conversion

1. A system comprising:

a network connector;

a non-transitory computer storage medium storing instructions that are operable, when executed by one or more computers, to cause the one or more computers to perform operations comprising:

receiving, from a client device, data specifying, for the client device, a first format for one or more messages receivable from the client device and a response format for one or more response messages for sending to the client device;

receiving a first message in the first format from the client device, the first message including information sufficient to cause a target service to execute an operation;

identifying, from the first message, the target service by parsing the first message according to the data specifying the first format;

determining, based on the target service that is identified, a second format;

generating a second message in the second format prescribed by the target service using the first message, the second message including information sufficient to cause the target service to execute the operation;

sending the second message to the target service over the network connector; and

sending, to the client device, a response message in the response format;

wherein the one or more computers are configured to:

receive messages in a plurality of different formats and that specify respective corresponding target services, and

generate, for each received message, a corresponding message based on a format corresponding to a respective target service, and

wherein the messages include at least two messages having different formats and identifying the same corresponding target service.

2. The system of claim 1 , further comprising:

receiving results from the target service in a first return format; and

generating results in a second return format, the second return format selected based on a sender of the first message.

3. The system of claim 2 , further comprising:

identifying an error code and an error message within the results;

generating an error in a format specified by the sender; and

sending the error message to the sender.

4. The system of claim 1 , further comprising:

identifying at least one error returned from the target service; and

providing the error to a sender of the first message in a second error format, the second error format determined based on the sender.

5. The system of claim 1 , further comprising:

authenticating the sending using a first authentication method different from a second authentication method used in the second message.

6. The system of claim 1 , wherein the system receives request from a sender over a network.

7. The system of claim 1 , wherein the system is operated by a sender of the first message.

8. The system of claim 1 , wherein the target service is a RESTful service.

9. A computer-implemented method comprising:

receiving, by a computer system and from a client device, data specifying, for the client device, a first format for one or more messages receivable from the client device and a response format for one or more response messages for sending to the client device;

receiving, by the computer system, a first message in the first format from the client device, the first message including information sufficient to cause a target service to execute an operation;

identifying, from the first message, the target service by parsing the first message according to the data specifying the first format;

determining, based on the target service that is identified, a second format;

generating, by the computer system, a second message in the second format prescribed by the target service using the first message, the second message including information sufficient to cause the target service to execute the operation;

sending the second message to the target service over a network connector; and

sending, to the client device, a response in the response format;

wherein the computer system is configured to:

receive messages in a plurality of different formats and that specify respective corresponding target services, and

generate, for each received message, a corresponding message based on a format corresponding to a respective target service, and

wherein the messages include at least two messages having different formats and identifying the same corresponding target service.

10. The computer-implemented method of claim 9 , further comprising:

receiving results from the target service in a first return format; and

generating results in a second return format, the second return format selected based on a sender of the first message.

11. The computer-implemented method of claim 10 , further comprising:

identifying an error code and an error message within the results;

generating an error in a format specified by the sender; and

sending the error message to the sender.

12. The computer-implemented method of claim 9 , further comprising:

identifying at least one error returned from the target service; and

providing the error to a sender of the first message in a second error format, the second error format determined based on the sender of the first message.

13. The computer-implemented method of claim 9 , further comprising:

authenticating the sending using a first authentication method different from a second authentication method used in the second message.

14. The computer-implemented method of claim 9 , wherein the target service is a RESTful service.

15. A non-transitory computer storage medium encoded with computer program instructions that when executed by one or more computers cause the one or more computers to perform operations comprising:

receiving, from a client device, data specifying, for the client device, a first format for one or more messages receivable from the client device and a response format for one or more response messages for sending to the client device;

receiving a first message in the first format from the client device, the first message including information sufficient to cause a target service to execute an operation;

identifying, from the first message, the target service by parsing the first message according to the data specifying the first format;

determining, based on the target service that is identified, a second format;

generating a second message in the second format prescribed by the target service using the first message, the second message including information sufficient to cause the target service to execute the operation;

sending the second message to the target service over the network connector; and

sending, to the client device, a response message in the response format;

wherein the one or more computers are configured to:

receive messages in a plurality of different formats and that specify respective corresponding target services, and

generate, for each received message, a corresponding message based on a format corresponding to a respective target service, and

wherein the messages include at least two messages having different formats and identifying the same corresponding target service.

16. The non-transitory computer storage medium of claim 15 , further comprising:

receiving results from the target service in a first return format; and

generating results in a second return format, the second return format selected based on a sender of the first message.

17. The non-transitory computer storage medium of claim 16 , further comprising:

identifying an error code and an error message within the results;

generating an error in a format specified by the sender; and

sending the error message to the sender.

18. The non-transitory computer storage medium of claim 16 , further comprising:

identifying at least one error returned from the target service; and

providing the error to the sender in a second error format, the second error format determined based on the sender.

19. The non-transitory computer storage medium of claim 15 , further comprising:

authenticating the sending using a first authentication method different from a second authentication method used in the second message.

20. The non-transitory computer storage medium of claim 15 , wherein the target service is a RESTful service.
