FetchToken - Call Reference - eBay Trading Web Services

FetchToken

Retrieves user token. The call can be used to get a token only after a user, at an eBay sign-in page, gives consent for the token to be generated. After token retrieval, the token can be used to authenticate other calls made on behalf of the user.

Argument	Type	Reqd?	Meaning
Standard Input Fields [Jump to call-specific fields]
ErrorLanguage	string	Optional	Use ErrorLanguage to return error strings for the call in a different language from the language commonly associated with the site that the requesting user is registered with. Specify the standard RFC 3066 language identification tag (e.g., en_US).

MessageID	string	Optional	In most cases, all calls support a MessageID element in the request and a CorrelationID element in the response. If you pass a message ID in a request, we will return the same value in CorrelationID in the response. You can use this for tracking that a response is returned for every request and to match particular responses to particular requests. If you do not pass MessageID in the request, CorrelationID is not returned. Note: GetCategories, GetAttributesCS, GetCategory2CS, GetAttributesXSL, GetProductFinder, GetProductFinderXSL, and GetProductSearchPage are designed to retrieve very large sets of metadata that change once a day or less often. To improve performance, these calls return cached responses when you request all available data (with no filters). When this occurs, the MessageID and CorrelationID fields aren't applicable. However, if you specify an input filter to reduce the amount of data returned, the calls retrieve the latest data (not cached). When this occurs, MessageID and CorrelationID are applicable.
Version	string	Conditional	The version number of the API code that you are programming against (e.g., 549). The version you specify for a call has these basic effects: - It indicates the version of the code lists and other data that eBay should use to process your request. - It indicates the schema version you are using. You need to use a version that is greater than or equal to the lowest supported version. For the SOAP API: If you are using the SOAP API, this field is required. Specify the version of the WSDL your application is using. For the XML API: If you are using the XML API, this field has no effect. Instead, specify the version in the X-EBAY-API-COMPATIBILITY-LEVEL HTTP header. (If you specify Version in the body of an XML API request and it is different from the value in the HTTP header, eBay returns an informational warning that the value in the HTTP header was used instead.) See: HTTP Headers (XML API Only) eBay Schema Versioning Strategy Lowest Supported Version
WarningLevel	WarningLevelCodeType	Optional	Controls whether or not to return warnings when the application passes unrecognized or deprecated elements in a request. An unrecognized element is one that is not defined in any supported version of the schema. Schema element names are case-sensitive, so using WarningLevel can also help you remove any potential hidden bugs within your application due to incorrect case or spelling in field names before you put your application into the Production environment. WarningLevel only validates elements; it doesn't validate XML attributes. It also doesn't control warnings related to user-entered strings or numbers, or warnings for logical errors. We recommend that you only use this during development and debugging. Do not use this in requests in your production code. Applicable values: • High (in) Return warnings when the application passes unrecognized or deprecated elements in a request. • Low (in) Do not return warnings when the application passes unrecognized or deprecated elements in a request. This is the default value if WarningLevel is not specified. See Warning Level.
Call-specific Input Fields
IncludeRESTToken	boolean	Optional	Specified if you want to retrieve a REST token for a user.
SecretID	string	Optional	A value that is associated with the token retrieval request. SecretID is defined by the application, and is passed in redirect URL to the eBay signin page. eBay recommends using a UUID for the secret ID value. You must also set Username (part of the RequesterCredentials) for the particular user of interest. SecretID and Username are not required if SessionID is present.
SessionID	string	Optional	A value that is associated with the token retrieval request. The session ID is generated by eBay by the application making GetSessionID call, and is passed in redirect URL to the eBay signin page. The advantage of using SessionID is that it does not require UserID as part of the FetchToken request. SessionID is not required if SecretID is present.

Return Value	Type	Returned?	Meaning
Standard Output Fields [Jump to call-specific fields]
Ack	AckCodeType	Always	A token representing the application-level acknowledgement code that indicates the response status (e.g., success). The AckCodeType list specifies the possible values for Ack. Applicable values: • CustomCode (out) Reserved for internal or future use. • Failure (out) Request processing failed • Success (out) Request processing succeeded • Warning (out) Request processing completed with warning information being included in the response message (Not all values in AckCodeType apply to this field.)
Build	string	Always	This refers to the specific software build that eBay used when processing the request and generating the response. This includes the version number plus additional information. eBay Developer Support may request the build information when helping you resolve technical issues.
CorrelationID	string	Conditionally	In most cases, all calls support a MessageID element in the request and a CorrelationID element in the response. If you pass a message ID in a request, we will return the same value in CorrelationID in the response. You can use this for tracking that a response is returned for every request and to match particular responses to particular requests. If you do not pass MessageID in the request, CorrelationID is not returned. Note: GetCategories, GetAttributesCS, GetCategory2CS, GetAttributesXSL, GetProductFinder, GetProductFinderXSL, and GetProductSearchPage are designed to retrieve very large sets of metadata that change once a day or less often. To improve performance, these calls return cached responses when you request all available data (with no filters). When this occurs, the MessageID and CorrelationID fields aren't applicable. However, if you specify an input filter to reduce the amount of data returned, the calls retrieve the latest data (not cached). When this occurs, MessageID and CorrelationID are applicable.
Errors	ErrorType (repeatable)	Conditionally	A list of application-level errors (if any) that occurred when eBay processed the request. See Error Handling.
Errors.ErrorClassification	ErrorClassificationCodeType	Conditionally	API errors are divided between two classes: system errors and request errors. Applicable values: • CustomCode (out) Reserved for internal or future use. • RequestError (out) An error has occurred either as a result of a problem in the sending application or because the application's end-user has attempted to submit invalid data (or missing data). In these cases, do not retry the request. The problem must be corrected before the request can be made again. If the problem is due to something in the application (such as a missing required field), the application must be changed. If the problem is a result of end-user data, the application must alert the end-user to the problem and provide the means for the end-user to correct the data. Once the problem in the application or data is resolved, resend the request to eBay with the corrected data. • SystemError (out) Indicates that an error has occurred on the eBay system side, such as a database or server down. An application can retry the request as-is a reasonable number of times (eBay recommends twice). If the error persists, contact Developer Technical Support. Once the problem has been resolved, the request may be resent in its original form.
Errors.ErrorCode	token	Conditionally	A unique code that identifies the particular error condition that occurred. Your application can use error codes as identifiers in your customized error-handling algorithms.
Errors.ErrorParameters	ErrorParameterType (repeatable)	Conditionally	This optional element carries a list of context-specific error variables that indicate details about the error condition. These are useful when multiple instances of ErrorType are returned.
Errors.ErrorParameters [ attribute ParamID ]	string	Conditionally	The index of the parameter in the list of parameter types returned within the error type.
Errors.ErrorParameters.Value	string	Conditionally	The value of the variable (e.g., the attribute set ID)
Errors.LongMessage	string	Conditionally	A more detailed description of the condition that raised the error.
Errors.SeverityCode	SeverityCodeType	Conditionally	Indicates whether the error is a severe error (causing the request to fail) or an informational error (a warning) that should be communicated to the user. Applicable values: • CustomCode (out) Reserved for internal or future use • Error (out) Application-level error • Warning (out) Warning or informational error
Errors.ShortMessage	string	Conditionally	A brief description of the condition that raised the error.
Timestamp	dateTime	Always	This value represents the date and time when eBay processed the request. The time zone of this value is GMT and the format is the ISO 8601 date and time format (YYYY-MM-DDTHH:MM:SS.SSSZ). See Time Values in the eBay Web Services guide for information about this time format and converting to and from the GMT time zone. Note: GetCategories, GetAttributesCS, GetCategory2CS, GetAttributesXSL, GetProductFinder, GetProductFinderXSL, and GetProductSearchPage are designed to retrieve very large sets of metadata that change once a day or less often. To improve performance, these calls return cached responses when you request all available data (with no filters). When this occurs, this time value reflects the time the cached response was created. Thus, this value is not necessarily when the request was processed. However, if you specify an input filter to reduce the amount of data returned, the calls retrieve the latest data (not cached). When this occurs, this time value does reflect when the request was processed.
Version	string	Always	The version of the response payload schema. Indicates the version of the schema that eBay used to process the request. See "Standard Data for All Calls" in the eBay Web Services Guide for information on using the response version when troubleshooting "CustomCode" values that appear in the response.
Call-specific Output Fields
eBayAuthToken	string	Always	The authentication token for the user. See Authentication & Authorization.
HardExpirationTime	dateTime	Always	Date and time at which the token returned in eBayAuthToken expires and can no longer be used to authenticate the user for that application.
RESTToken	string	Conditionally	The REST authentication token for the user.
