Automatic Mail-Merge Document Creation Using Zoho CRM APIs

Automatic Mail-Merge Document Creation Using Zoho CRM APIs

Efficient communication and personalized document generation are crucial for maintaining strong customer relationships in your business. Manual document generation can be time-consuming, repetitive and error-prone, decreasing productivity and customer satisfaction. You can solve this with automatic document generation by creating merged documents from predefined mail merge templates.
With Zoho CRM's mail merge templates you can create personalized documents, including forms, envelopes, and letters, by utilizing variables also known as merge fields. These templates enable you to merge data from variables, ensuring accurate information is incorporated into the documents without the need for manual data entry for each record. For additional information, please consult the guidelines on Managing Mail Merge Templates. 

In Zoho CRM, you can automate document generation using its mail merge template APIs. You can send, sign, and download customized documents automatically. 
Send Mail Merge API : To send emails to users using mail merge template. You can also attach files either as inline images or separate attachments with the email through the API.
Sign Mail Merge API : To sign and approve a merged document.
Download Mail Merge API: To download a mail merged document.

Let us discuss two use cases where these APIs are used. Assume you manage your business for a technological company, Zylker Technologies, using Zoho CRM. 

Prerequisites
  • Create a connector with required scopes. For the below use cases a connector with the below scopes was created -ZohoSign.documents.ALL, ZohoCRM.modules.ALL, ZohoWriter.documentEditor.ALL, ZohoWriter.Merge.ALL, ZohoCRM.settings.mailmerge.CREATE

Use Case 1: Using Mail Merge APIs for sending Letter of Intent for customers
 Let us consider a scenario where you want to send a LOI (Letter of Intent) to be signed by your customer. A Letter of Intent is a formal document that contains a preliminary agreement and commitment to move forward with the deal, outlining key terms and conditions. You can create a mail merge template for your LOI with merge fields from your Customer module. You can find mail merge templates in Zoho CRM UI under Setup > Customization > Templates > Mail Merge. Refer the below image for a sample LOI mail merge template. 

Sample Mail Merge Template for Letter of Intent

Note that the merge fields given in the mail merge template are fields from Accounts module (renamed as Customers) with additional custom fields.
You can automate sending the LOI to your customer using a custom button with an associated function for the Customers module. In this case, a custom button "send LOI" is added as shown in the screenshot below.

The below function calls sign mail merge API which sends the merged letter of intent document to your customer for signing.  The customer will receive an email notification containing the document which can be signed using Zoho Sign. Sign mail merge API's response includes a Zoho Writer document link that can be used to track the signing status. In the below function, the system will send mail to the customer along with the mail-merged document for them to sign, and it will store the link to track the sign status in a custom URL field named Document Sign Details.  This field allows you to access and review the document from your record conveniently.

customerMap = zoho.crm.getRecordById("Accounts",customerId.toLong());
name = customerMap.get("Account_Name");
to_email = customerMap.get("customer_Email");
merge_template_name = "LOI";
//Replace with your mail merge template name
info name;
info to_email;
input_json = "{'sign_mail_merge':[{'mail_merge_template':{'name':'" + merge_template_name + "'},'file_name':'letterofintent','sign_in_order':false,'signers':[{'recipient_name':'" + name + "','action_type':'sign','recipient':{'type':'email','value':'" + to_email + "'}}]}]}";
header_data = Map();
header_data.put("Content-Type","application/json");
response = invokeurl
[
url :"https://www.zohoapis.com/crm/v5/Accounts/" + customerId.toLong() + "/actions/sign_mail_merge"
type :POST
parameters:input_json
connection:"zylkercrm"
];
//Replace above connection name with your connection name
info response;
details = response.getJSON("sign_mail_merge").toJSONList();
link = "";
for each  detail in details
{
link = detail.get("details").get("report_link");
info link;
}
mp = Map();
mp.put("Document_Sign_Details",link);
update = zoho.crm.updateRecord("Accounts",customerId.toLong(),mp);
return "";

The system sends a merged document, as shown in the screenshot below, to the customer.

Use case 2: Using mail merge API for sending different types of SLA 
Assume that in Zylker Technologies, when you sell a product, your customer can opt for different types of after sales support . A check list field - Support Type - indicates type of support - Standard or Premium.  SLA document(Service Level Agreement) is a contract between you and your customer that defines level of service and the metrics used to measure the service.The service level provided to different customers will be different based on the kind of support they opted for and you need to send different SLA document based on this.  This can be achieved by maintaining two SLA mail merge templates. 
Similar to use case 1, a custom button can invoke the below function and in the function, a mail merge template is selected based on the type of service provided. The support_Type fields gets the value of the "Support Type" check list. Merge mail template is decided based on this field and send mail merge API is called to send the merged document. After sending the mail with appropriate mail merge template document, the function downloads the merged document and uploads it to the Attachments related list. 
Using download mail merge API, the merged document is obtained and then attached to the Contacts module with the attachFile function.


customerMap = zoho.crm.getRecordById("Accounts",customerId.toLong());
to_email = customerMap.get("customer_Email");
from_email = customerMap.get("Owner").get("email");
support_Type = customerMap.get("Support_Type");
if (support_Type == "Premium" )
{
merge_template_name = "SLA_Premium";
}
else 
{
merge_template_name = "SLA_Std";
}
//Replace above merge template names with your merge template names
input_json = "{'send_mail_merge':[{'mail_merge_template':{'name':'" + merge_template_name + "'},'from_address':{'type':'email','value':'" + from_email + "'},'to_address':[{'type':'email','value':'" + to_email + "'}],'subject':'Hi there','type':'attachment','attachment_name':'testdocument','message':'Big Deal'}]}";
header_data = Map();
header_data.put("Content-Type","application/json");
response = invokeurl
[
url :"https://www.zohoapis.com/crm/v5/Accounts/" + customerId + "/actions/send_mail_merge"
type :POST
parameters:input_json
connection:"zylkercrm"
];
//Replace above connection name with your connection name
input_json = "{'download_mail_merge':[{'mail_merge_template':{'name':'" + merge_template_name + "'},'output_format':'pdf'}]}";
header_data = Map();
header_data.put("Content-Type","application/json");
//The merged document is stored to file_object
file_object = invokeurl
[
url :"https://www.zohoapis.com/crm/v5/Accounts/" + customerId.toLong() + "/actions/download_mail_merge"
type :POST
parameters:input_json
connection:"zylkercrm"
];
//Replace above connection name with your connection name
response = zoho.crm.attachFile("Accounts",customerId,file_object);
return "";

The benefits of using the mail merge template APIs from Zoho CRM, which enable automated document generation, are highlighted in this article. These APIs enable the easy customization of the documents like Letters of Intent (LOIs), Service Level Agreements (SLAs), Request for Proposal (RFPs), etc. Businesses can increase efficiency, accuracy, and customer happiness by automating this procedure.

We need to be able to hire people for a fixed period of time, after which they would become 'available' again.  How do we go about doing this?

However, it's now 2024, and in-line editing from grids is just a basic expectation.
