**Receiving from a G address**

Using Horizon's `accounts/{acc_id}/transactions` endpoint ([example](https://horizon-testnet.stellar.org/accounts/GBLVHX33XGOBDOXK7ERDL34NVH6WW7VTT2OBAHPJ7G3D423HBG5NOMY7/transactions))

The memo field will be present in the response.

The guide’s earlier example memo ID is 123456789, but this sample response uses "memo": "12345" (and matching memo_bytes). To avoid confusion, consider keeping the memo value consistent with the memo ID used in the surrounding explanation (or update the earlier example values accordingly).

The code block is tagged as json but includes ... placeholders, which makes it invalid JSON and can be confusing for readers (and may break any JSON-aware rendering/linting). Consider either making the snippet valid JSON (e.g., replace placeholders with string values like "..." / include minimal required fields) or switch the fence language to something non-JSON (e.g., text) if you intend it to be illustrative/pseudocode.

In this example, fields like id, paging_token, successful, hash, etc. are shown nested under _links, but in Horizon’s transaction representation these are top-level transaction fields and _links only contains link objects (self/account/ledger/etc.). This structure mismatch could mislead readers; consider restructuring the snippet to match the documented Transaction object shape (see docs/data/apis/horizon/api-reference/resources/transactions/object.mdx for an example).

**Receiving from a Contract Account**

This code block is also labeled json but contains ..., and ... placeholders, which makes it invalid JSON. Consider either providing a valid (possibly truncated) JSON object (e.g., keep placeholders as quoted strings / remove the leading ...,) or changing the fence language away from json if it’s not meant to be copy-pastable.
