The setTabs API enables you to set initial values for certain fields in the Agreement. The value you set using the setTabs API is displayed on the envelope. Set the initial values using this API before you initiate the eSignature request.

set Tabs for each Recipient: Provides an initial set of corresponding values for each tag type for a recipient when the request is sent to DocuSign. These are the initial values that are viewable and editable in the document you send to the signer for signature.

Before using the APIs ensure the following:

• Ensure that the DocuSign Custom Classes with the field Add Recipient Tabs Callback Classispopulatedwith the callback class name, DocuSignEnvelopeSetRecipientTabs2Imp.
• Ensure that you select theRecipientTabs Enabled checkbox under the DocuSign System Properties.
• In the custom callback class, set the value and the anchor string for the custom tag, getRecipientTabsmethodiswherewe set the value and the anchor string for the custom tag that we want to prepopulate.

In the Custom Callback class, the getRecipientTabs method is where you set the value and the anchor string for the custom tag that you want to prepopulate. So, if you want to populate a text tab with some value, you should initialize the text tab in the getRecipientTabs method such as Apttus_DocuApi.DocuSignUtil.textTab objTextTab = new Apttus_DocuApi.DocuSignUtil.textTab(iRecipientId,'This Value','40','0','0'.The second parameter is the value that you need to set for the custom text tag, so for above example, the text tag has a value - 'This Value', when it shows up in DocuSign. You can set it to a dynamic value by pulling up any field through SOQL using the parentId. Then, while setting the anchor string for the tag, you can define what anchor string you are going to use in the template. Suppose you want to use \t {r}\anchortag, this is what you put in the custom class- objTextTab.anchorString = '\\t'+iRecipientId; objRecipientTabs.addTextTab(objTextTab). You then need to use the tag \t1\, \t2\ in the document that you are sending for signature, and you need to have the tag \t{r} \ defined under the DocuSign account under custom tags.

The snippet below enables you to set default values for DocuSign tags.
