Google Sheets Stream
Since Camel 2.23
The Google Sheets component provides access to https://sheets.google.com/[Sheets] via the https://developers.google.com/sheets/api/reference/rest/[Google Sheets Web APIs].
Google Sheets uses the https://developers.google.com/accounts/docs/OAuth2[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 https://developers.google.com/google-apps/sheets/auth[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 https://developers.google.com/oauthplayground[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> <version>2.23.0</version> </dependency>
URI Format
The Google Sheets Component uses the following URI format:
google-sheets-stream://apiName?[options]
GoogleSheetsStreamComponent
The Google Sheets Stream component supports 3 options, which are listed below.
Name | Description | Default | Type |
---|---|---|---|
configuration (consumer) |
To use the shared configuration |
GoogleSheetsStream Configuration |
|
clientFactory (advanced) |
To use the GoogleSheetsClientFactory as factory for creating the client. Will by default use BatchGoogleSheetsClientFactory |
GoogleSheetsClient Factory |
|
resolveProperty Placeholders (advanced) |
Whether the component should resolve property placeholders on itself when starting. Only properties which are of String type can use property placeholders. |
true |
boolean |
The Google Sheets Stream endpoint is configured using URI syntax:
google-sheets-stream:apiName
with the following path and query parameters:
Query Parameters (32 parameters):
Name | Description | Default | Type |
---|---|---|---|
accessToken (consumer) |
OAuth 2 access token. This typically expires after an hour so refreshToken is recommended for long term usage. |
String |
|
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 |
|
clientSecret (consumer) |
Client secret of the sheets application |
String |
|
includeGridData (consumer) |
True if grid data should be returned. |
false |
boolean |
majorDimension (consumer) |
Specifies the major dimension that results should use.. |
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. |
0 |
int |
range (consumer) |
Specifies the range of rows and columns in a sheet to get data from. |
String |
|
refreshToken (consumer) |
OAuth 2 refresh token. Using this, the Google Calendar component can obtain a new accessToken whenever the current one expires - a necessity if the application is long-lived. |
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 |
|
sendEmptyMessageWhenIdle (consumer) |
If the polling consumer did not poll any files, you can enable this option to send an empty message (no body) instead. |
false |
boolean |
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. |
FORMATTED_VALUE |
String |
exceptionHandler (consumer) |
To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored. |
ExceptionHandler |
|
exchangePattern (consumer) |
Sets the exchange pattern when the consumer creates an exchange. |
ExchangePattern |
|
pollStrategy (consumer) |
A pluggable org.apache.camel.PollingConsumerPollingStrategy allowing you to provide your custom implementation to control error handling usually occurred during the poll operation before an Exchange have been created and being routed in Camel. |
PollingConsumerPoll Strategy |
|
synchronous (advanced) |
Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported). |
false |
boolean |
backoffErrorThreshold (scheduler) |
The number of subsequent error polls (failed due some error) that should happen before the backoffMultipler should kick-in. |
int |
|
backoffIdleThreshold (scheduler) |
The number of subsequent idle polls that should happen before the backoffMultipler should kick-in. |
int |
|
backoffMultiplier (scheduler) |
To let the scheduled polling consumer backoff if there has been a number of subsequent idles/errors in a row. The multiplier is then the number of polls that will be skipped before the next actual attempt is happening again. When this option is in use then backoffIdleThreshold and/or backoffErrorThreshold must also be configured. |
int |
|
delay (scheduler) |
Milliseconds before the next poll. You can also specify time values using units, such as 60s (60 seconds), 5m30s (5 minutes and 30 seconds), and 1h (1 hour). |
500 |
long |
greedy (scheduler) |
If greedy is enabled, then the ScheduledPollConsumer will run immediately again, if the previous run polled 1 or more messages. |
false |
boolean |
initialDelay (scheduler) |
Milliseconds before the first poll starts. You can also specify time values using units, such as 60s (60 seconds), 5m30s (5 minutes and 30 seconds), and 1h (1 hour). |
1000 |
long |
runLoggingLevel (scheduler) |
The consumer logs a start/complete log line when it polls. This option allows you to configure the logging level for that. |
TRACE |
LoggingLevel |
scheduledExecutorService (scheduler) |
Allows for configuring a custom/shared thread pool to use for the consumer. By default each consumer has its own single threaded thread pool. |
ScheduledExecutor Service |
|
scheduler (scheduler) |
To use a cron scheduler from either camel-spring or camel-quartz2 component |

true |
boolean |
timeUnit (scheduler) |
Time unit for initialDelay and delay options. |
MILLISECONDS |
TimeUnit |
useFixedDelay (scheduler) |
Controls if fixed delay or fixed rate is used. See ScheduledExecutorService in JDK for details. |
true |
boolean |

When using Spring Boot make sure to use the following Maven dependency to have support for auto configuration:
<dependency>
<groupId>org.apache.camel</groupId>
<artifactId>camel-google-sheets-starter</artifactId>
<version>x.x.x</version>
<!-- use the same version as your Camel core version -->
