GetSessionID
Use this call to retrieve a SessionID, which is a unique identifier that you use for authentication during the token-creation process. You must have a valid SessionID value in order to make a FetchToken request.
See Getting a Token via FetchToken for a step-by-step description of retrieving and using a SessionID.
Unlike other Trading API calls, GetSessionID requires your application keys (App ID, Dev ID, and Cert ID), as well as an RuName value. Include the application keys in the SOAP header for SOAP requests, or in the HTTP header for XML requests. Register your RuName with eBay. For details on RuNames, see Setting Up an Application to Receive Tokens.
Once you obtain the SessionID, you can use it to construct the URL that sends a user to the eBay consent flow. Also, use the SessionID value when you retrieve the user token with FetchToken.
You can test GetSessionID in the Sandbox. You'll need to create at least one test user to do that. For information about creating and using test users, see Testing in the SandBox. Use the following URL for the sign-in and consent page for the Sandbox environment:
https://signin.sandbox.ebay.com/ws/eBayISAPI.dll?SignIn&runame=MyRuName&SessID=MyURLEncodedSessionID
Note that in the sign-in URL, the value of the session ID must be URL-encoded.

Call-specific Input Fields [Jump to standard fields] |
RuName | string | Required | The eBay Registered URL must be specified in this field. An eBay Registered URL is created and associated with a developer's Sandbox or Production key set by logging into the user's developer account on developer.ebay.com and going to the User Tokens page. The RuName value passed in this field must match the one specified for the specific Sandbox or Production key set being used to make the GetSessionID call. For more information on adding and registering your RuName, see the Setting Up an Application to Receive Tokens tutorial. |
Standard Input 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. Below are some examples from different countries.
|
||||||||||||||||||||||||||||||||||||||||
MessageID | string | Optional |
Most Trading API calls support a MessageID element in the request and a CorrelationID element in the response. If you pass in a MessageID in a request, the same value will be returned in the CorrelationID field in the response. Pairing these values can help you track and confirm that a response is returned for every request and to match specific responses to specific requests. If you do not pass a MessageID value in the request, CorrelationID is not returned. Note: GetCategories is 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., 1149). The version you specify for a call has these basic effects:
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:
|
||||||||||||||||||||||||||||||||||||||||
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 performed in the Production environment. Applicable values: High if the user wishes to receive warnings when the application passes unrecognized or deprecated elements in an API call request. Setting the WarningLevel value to High is not recommended in a production environment. Instead, it should only be used during the development/debugging stage.Low if the user does not wish to receive warnings when the application passes unrecognized or deprecated elements in an API call request. This is the default value if WarningLevel is not specified in the call request.See Warning Level. |

Return Value | Type | Occurrence | Meaning |
---|
Call-specific Output Fields [Jump to standard fields] |
SessionID | string | Always | A 40-character identifier supplied by eBay to an application. Used to confirm the identities of the user and the application in a URL redirect during the process in which the user agrees to let the application wield a user token that grants the application the right to access eBay data on behalf of the user. Subsequently also used as input for the FetchToken API call. The SessionID value is valid for five minutes after it is retrieved. |
Standard Output 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 the Ack field.
Applicable values: (Not all values in AckCodeType apply to this field.) Code so that your app gracefully handles any future changes to this list. |
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 |
Most Trading API calls support a MessageID element in the request and a CorrelationID element in the response. If you pass in a MessageID in a request, the same value will be returned in the CorrelationID field in the response. Pairing these values can help you track and confirm that a response is returned for every request and to match specific responses to specific requests. If you do not pass a MessageID value in the request, CorrelationID is not returned. Note: GetCategories is 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 | Conditionally,
repeatable: [0..*] |
A list of application-level errors (if any) that occurred when eBay processed the request. |
Errors.ErrorClassification | ErrorClassificationCodeType | Conditionally |
API errors are divided between two classes: system errors and request errors.
Applicable values: Code so that your app gracefully handles any future changes to this list. |
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.
See Errors By Number. |
Errors.ErrorParameters | ErrorParameterType | Conditionally,
repeatable: [0..*] |
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 | 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.Value | string | Conditionally | This is the value of the request parameter noted in the ParamID attribute. So, if the ParamID value was ItemID, the value in this field would be the actual value of that ItemID. |
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: If the source of the problem is within the application (such as a missing required element), change the application before you retry the request.
See the Error handling section of the Making a Trading API call guide for more information. When a warning occurs, the error is returned in addition to the business data. In this case, you do not need to retry the request (as the original request was successful). However, depending on the cause or nature of the warning, you might need to contact either the end user or eBay to effect a long term solution to the problem to prevent it from reoccurring in the future. Code so that your app gracefully handles any future changes to this list. |
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 the Time Values section in the eBay Features Guide for information about this time format and converting to and from the GMT time zone. Note: GetCategories and other Trading API calls 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 the Standard Data for All Calls section in the eBay Features Guide for information on using the response version when troubleshooting CustomCode values that appear in the response. |
