Google Sheets Stream

Since Camel 2.23

Only consumer is supported

The Google Sheets component provides access to Sheets via the Google Sheets Web APIs.

Google Sheets uses the OAuth 2.0 protocol for authenticating a Google account and authorizing access to user data. Before you can use this component, you will need to create an account and generate OAuth credentials. Credentials comprise of a clientId, clientSecret, and a refreshToken. A handy resource for generating a long-lived refreshToken is the OAuth playground.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
        <groupId>org.apache.camel</groupId>
        <artifactId>camel-google-sheets</artifactId>
        <!-- use the same version as your Camel core version -->
        <version>x.x.x</version>
</dependency>

URI Format

The Google Sheets Component uses the following URI format:

google-sheets-stream://apiName?[options]

Component options

The Google Sheets Stream component supports 17 options, which are listed below.

Name Description Default Type

applicationName (consumer)

Google sheets application name. Example would be camel-google-sheets/1.0

String

bridgeErrorHandler (consumer)

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

boolean

clientId (consumer)

Client ID of the sheets application

String

configuration (consumer)

To use the shared configuration

GoogleSheetsStreamConfiguration

includeGridData (consumer)

True if grid data should be returned.

false

boolean

majorDimension (consumer)

Specifies the major dimension that results should use.. There are 3 enums and the value can be one of: ROWS, COLUMNS, DIMENSION_UNSPECIFIED

ROWS

String

maxResults (consumer)

Specify the maximum number of returned results. This will limit the number of rows in a returned value range data set or the number of returned value ranges in a batch request.

int

range (consumer)

Specifies the range of rows and columns in a sheet to get data from.

String

scopes (consumer)

Specifies the level of permissions you want a sheets application to have to a user account. See https://developers.google.com/identity/protocols/googlescopes for more info.

List

splitResults (consumer)

True if value range result should be split into rows or columns to process each of them individually. When true each row or column is represented with a separate exchange in batch processing. Otherwise value range object is used as exchange junk size.

false

boolean

spreadsheetId (consumer)

Specifies the spreadsheet identifier that is used to identify the target to obtain.

String

valueRenderOption (consumer)

Determines how values should be rendered in the output. There are 3 enums and the value can be one of: FORMATTED_VALUE, UNFORMATTED_VALUE, FORMULA

accessToken (security)

OAuth 2 access token. This typically expires after an hour so refreshToken is recommended for long term usage.

String

clientSecret (security)

Client secret of the sheets application

String

refreshToken (security)

By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.
