Proposed workflow

Customer sync test

Planning example. Stacksync support for the required connection and record operations needs a technical review.

Starting eventA change involving Dynamics 365 Business Central Customers or SendGrid Contacts needs a defined result in the other system.

  1. Start with Dynamics 365 Business Central Customers and SendGrid Contacts. Use the record-matching and field-ownership rules from your mapping worksheet.

  2. Resolve person or company type, legal entity, business role, and any billing account before transactions.

  3. Test a normal update and one failed or repeated update in the supported direction. Keep both record IDs with the test results.

What to verifyTest an individual buyer, a company buyer, and one company with multiple billing relationships. Do not merge these into a single generic contact.

CustomersProposed record; confirm Stacksync object support.Customer identity assessmentContactsDocumented record: Read: Supported. Write: Not available (read-only connector).Determine whether each customer represents an individual, a company, or a business-unit relationship before matching it to a contact or organization. Retain the source customer ID and destination ID; names and email alone are insufficient.Separate the customer relationship from contact details, billing authority, and consent. Choose an owner for each field after identifying whether the customer is a person or company.

These relationships do not establish connector availability. Review the required connection and record operations with Stacksync.

Record coverage to review

Use documented coverage where available. Catalog record types are starting points for review and do not confirm Stacksync support.

Customer identity

Customers / Contacts

Before linking Dynamics 365 Business Central Customers to SendGrid Contacts, check whether the customer is an individual or a company. Match the correct record type in each system.

Planning example. Stacksync support for the required connection and record operations needs a technical review.

Dynamics 365 Business Central
Object support to establish
SendGrid
Documented record · Read: ✅ Supported. Write: Not available (read-only connector).
Record identity
Determine whether each customer represents an individual, a company, or a business-unit relationship before matching it to a contact or organization. Retain the source customer ID and destination ID; names and email alone are insufficient.
Field ownership
Separate the customer relationship from contact details, billing authority, and consent. Choose an owner for each field after identifying whether the customer is a person or company.

Fields to include

  • Source customer ID
  • Person/company classification
  • Legal entity or business unit
  • Destination identity reference
Record dependencies
Resolve person or company type, legal entity, business role, and any billing account before transactions.
Validation
Test an individual buyer, a company buyer, and one company with multiple billing relationships. Do not merge these into a single generic contact.
Recovery
Hold ambiguous customer matches for review and resolve customer type before retrying dependent records.

Compare integration approaches

Choose a method around one example record and the update your business needs. Use Customers / Contacts to review record matching and confirm Stacksync support for the required operations. Compare ongoing sync, a custom workflow, and a scheduled export against that requirement.

Stacksync managed sync

Best fit
Review compatibility with a Stacksync engineer using an example of the records and updates you need.
Operating responsibility
Fits ongoing record synchronization when the required operations are supported. Add workflow steps for approvals or business actions that go beyond copying fields.
Before you choose
Check record matching: Determine whether each customer represents an individual, a company, or a business-unit relationship before matching it to a contact or organization. Retain the source customer ID and destination ID; names and email alone are insufficient. Verify field coverage, deletion handling, and how changes are detected.

Native vendor integration

Best fit
A vendor-built integration may fit if it supports your Dynamics 365 Business Central and SendGrid record types.
Operating responsibility
Can reduce setup for a supported workflow. You may need another method for records or business steps it does not cover.
Before you choose
First check whether either vendor offers this integration. If available, verify Customers / Contacts, update direction, account tier, and related-record handling.

Custom API or workflow

Best fit
Consider when Dynamics 365 Business Central and SendGrid need a transformation, approval, or action outside a direct record sync.
Operating responsibility
Provides control over business steps; the team owns credentials, version changes, error queues, and reconciliation.
Before you choose
Verify endpoint permissions, pagination, quotas, duplicate detection, and failure recovery. Separate reading history from actions that send messages, grant access, or post transactions.

File or scheduled snapshot

Best fit
Consider for a one-time Dynamics 365 Business Central / SendGrid migration or a reporting need with an explicit freshness window.
Operating responsibility
Can simplify a bounded transfer; later changes and deletion history require another extraction or a separately designed incremental process.
Before you choose
Record the extraction cutoff, source IDs, encoding, date/number formats, and reconciliation totals.

Workflow scenarios and expected results

Customer sync test

Planning example. Stacksync support for the required connection and record operations needs a technical review.

Starting event: A change to the selected Customers or Contacts record needs a defined result in the other system.

  1. Start with Dynamics 365 Business Central Customers and SendGrid Contacts. Use the record-matching and field-ownership rules from your mapping worksheet.
  2. Resolve person or company type, legal entity, business role, and any billing account before transactions.
  3. Test a normal update and one failed or repeated update in the supported direction. Keep both record IDs with the test results.

Expected result: Test an individual buyer, a company buyer, and one company with multiple billing relationships. Do not merge these into a single generic contact.

If it fails: Hold ambiguous customer matches for review and resolve customer type before retrying dependent records.

Link communication history with Dynamics 365 Business Central context

This is an evaluation scenario; connector and operation support require confirmation.

Starting event: A communication in SendGrid needs an association with Customers or Vendors in Dynamics 365 Business Central.

  1. Select the communication records from Contacts and preserve message/call and thread IDs.
  2. Resolve the participant-to-business-record relationship explicitly; phone number or display name alone may be ambiguous.
  3. Keep history replication separate from sending a message, placing a call, or changing consent. Confirm a separate authorized operation for any action.

Expected result: Repeated delivery updates the same history record; a private conversation stays private; a history replay sends no new message.

If it fails: Check source delivery state and the destination relationship before retrying. Do not resend to repair an analytical or history discrepancy.

Initial load and acceptance testing

Keep both record IDs with the expected and actual result. Reconcile the same filters and time window in each system.

Customers / Contacts

Test case

Test an individual buyer, a company buyer, and one company with multiple billing relationships. Do not merge these into a single generic contact.

Expected result

The expected customer relationship is preserved with no duplicate action or unintended write.

Direction and permissions

Test case

Bring an example source record and the intended destination operation to the compatibility review. Confirm the supported route before granting write access.

Expected result

Only an approved, supported direction and permitted fields are written.

Freshness and reconciliation

Test case

Measure source and destination times for the selected records under normal load and a burst. Reconcile IDs and values using the same filters and cutoff.

Expected result

The process meets its agreed freshness target and reconciliation has no unexplained differences.

Failed updates, retries and recovery

Start with the failed record and the destination error, then inspect the source value, field requirements, and access.

Rejected or repeated customer change

Investigate

Inspect Dynamics 365 Business Central Customers and SendGrid Contacts, their IDs, and the destination error.

Next action

Hold ambiguous customer matches for review and resolve customer type before retrying dependent records.

A record type or update is unavailable

Investigate

Check the Dynamics 365 Business Central and SendGrid connector guides, account permissions, and any operations marked On Request.

Next action

Ask the integration team to confirm a supported way to handle that record. Verify whether it needs connector configuration or a separate workflow step.

Source and destination disagree after a retry

Investigate

Compare current source values, destination validation, identity mappings, and any side effects already completed.

Next action

Stacksync issue retry reads the current source state. Decide the intended state before retrying or reverting; reconcile downstream effects separately.

Read the Stacksync issues dashboard guide for retry and revert behavior.

Change detection and update delivery

How updates move between Dynamics 365 Business Central and SendGrid

See how each system detects changes and which updates the other system can receive. Each direction has its own permissions and record requirements.

Dynamics 365 Business Central SendGrid Direction not supported

Detect changesThis route requires read access from Dynamics 365 Business Central and write access to SendGrid; the documented connector restrictions do not permit it.

Apply updatesUse a supported direction or review a separate integration method for this requirement.

SendGrid Dynamics 365 Business Central Direction requires confirmation

Detect changesThe saved Stacksync guide does not specify the change-detection mechanism. Confirm it for the selected objects.

Apply updatesConfirm that Stacksync can create or update the records you need in Dynamics 365 Business Central.

Update timing and record limits
  • Measure initial-load and ongoing-change latency separately. Source detection, selected objects, account limits, and destination validation determine the observed delay.
  • Review write-back, deletion handling, update timing, and account limits with the integration team.
