Hello everyone!
We're back with another post in the Kaizen series.
We're grateful for the feedback we received from all of you!
One of the questions we received was "I would like to see the list of Purchase Orders in Zoho Books for a Deal in CRM."
We will discuss how to achieve this using the Queries feature in Zoho CRM.
Scenario
In many organizations, a single Deal in Zoho CRM may correspond to one or more Purchase Orders(POs) in Zoho Books. To get a real-time view of all POs associated with a Deal in CRM, we can leverage the Queries feature under Setup > Developer Hub > Queries, and custom related lists.
1. CRM and Zoho Books Integration
Zoho CRM and Books integration allows you to
- View POs, invoices, and payments for deals directly in CRM
- Synchronize financial data between CRM deals and Books POs
- Automate the mapping of deals to POs via custom fields
- Go to Setup > Developer Hub > Connections
- Create a connection to Books(OAuth) with the scopes ZohoBooks.contacts.All and ZohoBooks.purchaseorders.All.

2. Prerequisites
Before creating the query and automation, you must have the following ready:
- Zoho Books organization ID – needed for REST API calls.
- Custom field in Books PO module:
Field Name: CRM Deal ID
Type: Single-line
Purpose: Store the CRM deal ID that each PO relates to.
Why do we need this custom field?
By default, Books POs are not directly linked to CRM Deals. To bridge this gap, we create a custom single-line field(CRM Deal ID) in Books POs to store the CRM Deal’s record ID. This makes it possible to filter POs in queries(cf_crm_deal_id == {{deal_ID}}) and reliably display only the related POs in CRM.

You can store the record ID of the deal in CRM in this field either manually or via a custom function. When you use a custom function, use the Update a Purchase Order API to update the CRM Deal ID field in Books with the record ID of the deal in CRM. You can then associate this function to a button or automation to constantly update the PO in Books every time a deal in CRM is created or updated in CRM. You can also use Zoho Flow to achieve this instead of a function. - Trusted domain and source:
- Ensure you have added Books API domain to trusted domain for API calls.

- Add Zoho Books as the source of the query to get the PO details from Books. You can add the Books' organization ID as a parameter either here or while creating the query.

3. Single Deal, Multiple POs
Scenario
- A CRM deal requires multiple POs from different vendors.
- Each PO in Books stores the same Deal ID in the CRM Deal ID field.
- This allows a related list in CRM to show all POs associated with the deal.
Why a Single-line Field Works?
- Each PO references one deal.
- Queries in CRM can filter using cf_crm_deal_id == {{deal_ID}}. cf_crm_deal_id is the API name of the custom field in PO of Books. You can find it under Setup > Purchases > Purchase Orders > {the custom field} > Edit.
- Works reliably for related list display.
4. Creating a REST API Query in CRM
Since we will use Books API to get the list of POs, we will create a REST API type query.
- Go to Setup > Developer Hub > Queries > Create Query.
- Enter the details as shown in the following image:

- Choose the Books source that you added recently.
- Give a name for the query.
- The API name will be auto-populated, and the URL will be populated from the source.
- Enter the endpoint to access the resource from Books. In our case, purchaseorders.
- To filter based on the value in the CRM Deal ID field in Books, enter the parameter as cf_crm_deal_id and its value as a variable. This variable takes the Deal's record ID as the value during run time. This ensures that the query takes the deal residing in the CRM Deal ID(which is also the record ID of the deal in CRM) field in Books and filters only those POs related to this Deal.
- If you have not given org_id as a parameter while creating the source, include it here.
- Click Next. You will get a pop-up asking for the value to the variable cf_crm_deal_id. Give a value to see the query in action.
- The query returns the list of POs from Books that are related to this particular deal in CRM.
- Save the query.
5. Serializing(to return a table for the related list)
Serializer allows you to manipulate the response of the query using Javascript.
In our example, the raw response of the query will contain the POs from Books for a deal in CRM as an array with many fields.
For example, the deal with CRM record ID 3652397000017912047 has two POs in Books viz, PO-00001 and PO-00003. The raw response before serialization is as follows.
But, to associate this response with a related list, we don't need all the fields. We can use the serializer to modify this response and use only the required fields.
The following image shows the serialized response.
Click Save and configure the Schema.

Click Save to save the query.
6. Adding the Query to a Related List
Now that we have the query ready, let's associate this with a related list in the Deals module in CRM to contextually view the POs of the Deal in Books.
- Navigate to the Deals module in CRM.
- Click the three-dot icon on the right corner of the record, and click Add Related List. Alternatively, you can also click the Add Related List option on the left in the Related List pane.

- From the pop-up, select Queries.

- From the list of available queries, select the Get Purchase Orders query you created and click Associate.

- Give a name for the related list.
- Under Variable Mapping, type #(to view merge fields) to get the list of modules available. Choose Deals and the Deal Id field. This means that the record ID of the deal will be passed as the value of the cf_crm_deal_id variable at runtime. The query will then fetch the list of POs for this Deal ID from Books, and display it in this related list.

- Click Save and you will see the related list under the Related Lists section of the record.

- Reload the page to see the query in action.

Automation Options
You can automatically update the CRM Deal ID in Books POs when a deal is created or a PO is raised.
1. Using Function
- Function triggers on deal creation or a button click in CRM.
- Fetches the PO in Books and updates the CRM Deal ID field using the Books connection.
2. Using Zoho Flow
- Event: Deal created or updated in CRM.
- Action: Update the corresponding PO(s) in Books.
- Works without writing Deluge code.
Both methods require the Books connection and organization ID.
Summary/Best Practices
- Single Deal, Multiple POs: Use single-line CRM Deal ID field in Books.
- Queries and serializer: Filter POs based on cf_crm_deal_id == {{deal_ID}}.
- Automation: Use functions or Zoho Flow for real-time updates.
- Multi-Deal, Single PO: Not supported for related lists; use custom reporting instead.
This setup ensures that sales and finance teams can see all POs for a deal directly in CRM without manual reconciliation.
We hope this post answered your question and you found this useful.
Cheers!

Deleting unwanted ticket replies
Hello, In a Zoho Desk Ticket thread, sometimes one of the recipients has auto-reply activated. This creates a new message in the Ticket thread that not only pollutes the thread, but most importantly cannot be replied properly because usually auto-reply e-mails don't do "reply all", so the other recipients are not included. I want to delete such a message in the Ticket thread. I searched the help of Zoho Desk, but only found a way to mark as Spam (https://help.zoho.com/portal/kb/articles/marking-support-tickets-as-spam)

Zoho Calendar Integrated Into CRM?
I've searched around the forums but couldn't find anything addressing this . . . Is there a plan to integrate Zoho's stand alone calendar solution into Zoho CRM?

My preferred solution would be for ZCal to become the default calendar/event solution within Z CRM. Is this on the roadmap? Thanks
