Before trying the below tools, you will want to make sure you press the "Authorize" button below and provide the API Key you are shown when you open the "Local REST API" section of your Obsidian settings. All requests to the API require a valid API Key; so you won''t get very far without doing that.
When using this tool you may see browser security warnings due to your browser not trusting the self-signed certificate the plugin will generate on its first run. If you do, you can make those errors disappear by adding the certificate as a "Trusted Certificate" in your browser or operating system''s settings.

# Targeting a Sub-part of your Document
You can operate on a specific section of a note instead of the whole file by providing `Target-Type` and `Target` headers:
- Set `Target-Type` to `heading`, `block`, or `frontmatter`.
- Set `Target` to the name of the heading, block reference, or frontmatter field. If the target contains non-ASCII characters (e.g. accented letters), percent-encode the value (e.g. `H%C3%A9llo` for `Héllo`).
- For nested headings, use the `Target-Delimiter` header (default `::`) to separate levels.
You can also embed the target type and target directly in the URL path after the note identifier instead of using headers. The segment immediately following the note identifier is the target type, and the remaining segments form the target:
- `.../heading/My%20Section` is equivalent to supplying `Target-Type: heading` and `Target: My%20Section`.
- For nested headings, add additional path segments: `.../heading/My%20Section/Subsection` is equivalent to `Target: My%20Section::Subsection`.
- `.../frontmatter/fieldName` targets the `fieldName` frontmatter field.
- `.../block/abc123` targets the block with reference ID `abc123`.
When URL-embedded values are present they take priority over the corresponding headers.
# Retrieving Document Metadata
## Metadata
If you specify the header `Accept: application/vnd.olrapi.note+json`, will return a JSON representation of your note including parsed tag and frontmatter data as well as filesystem metadata.
## Document Map
If you specify the header `Accept: application/vnd.olrapi.document-map+json`, will return a JSON object outlining what PATCH targets exist. See "responses" below for details.

# How to Use & Examples
All of the below examples assume you have a document that looks like
this:
```markdown
---
alpha: 1
beta: test
delta:
zeta: 1
yotta: 1
gamma:
- one
- two
---
# Heading 1
This is the content for heading one
Also references some [[#^484ef2]]
## Subheading 1:1
Content for Subheading 1:1
### Subsubheading 1:1:1
### Subsubheading 1:1:2
Testing how block references work for a table.[[#^2c7cfa]]
Some content for Subsubheading 1:1:2
More random text.
^2d9b4a
## Subheading 1:2
Content for Subheading 1:2.
some content with a block reference ^484ef2
## Subheading 1:3
| City | Population |
| ------------ | ---------- |
| Seattle, WA | 8 |
| Portland, OR | 4 |
^2c7cfa
```
## Append, Prepend, or Replace Content Below a Heading
If you wanted to append the content "Hello" below "Subheading 1:1:1" under "Heading 1",
you could send a request with the following headers:
- `Operation`: `append`
- `Target-Type`: `heading`
- `Target`: `Heading 1::Subheading 1:1:1` (percent-encode any non-ASCII characters, e.g. `H%C3%A9llo` for `Héllo`)
- with the request body: `Hello`
The above would work just fine for `prepend` or `replace`, too, of course,
but with different results.
## Append, Prepend, or Replace Content to a Block Reference
If you wanted to append the content "Hello" below the block referenced by
"2d9b4a" above ("More random text."), you could send the following headers:
- `Operation`: `append`
- `Target-Type`: `block`
- `Target`: `2d9b4a`
- with the request body: `Hello`
The above would work just fine for `prepend` or `replace`, too, of course,
but with different results.
## Append, Prepend, or Replace a Row or Rows to/in a Table Referenced by a Block Reference
If you wanted to add a new city ("Chicago, IL") and population ("16") pair to the table above
referenced by the block reference `2c7cfa`, you could send the following
headers:
- `Operation`: `append`
- `Target-Type`: `block`
- `Target`: `2c7cfa`
- `Content-Type`: `application/json`
- with the request body: `[["Chicago, IL", "16"]]`
The use of a `Content-Type` of `application/json` allows the API
to infer that member of your array represents rows and columns of your
to append to the referenced table. You can of course just use a
`Content-Type` of `text/markdown`, but in such a case you''ll have to
format your table row manually instead of letting the library figure
it out for you.
You also have the option of using `prepend` (in which case, your new
row would be the first -- right below the table heading) or `replace` (in which
case all rows except the table heading would be replaced by the new row(s)
you supplied).
## Setting a Frontmatter Field
If you wanted to set the frontmatter field `alpha` to `2`, you could
send the following headers:
- `Operation`: `replace`
- `Target-Type`: `frontmatter`
- `Target`: `beep`
- with the request body `2`
If you''re setting a frontmatter field that might not already exist
you may want to use the `Create-Target-If-Missing` header so the
new frontmatter field is created and set to your specified value
if it doesn''t already exist.
You may find using a `Content-Type` of `application/json` to be
particularly useful in the case of frontmatter since frontmatter
fields'' values are JSON data, and the API can be smarter about
interpreting your `prepend` or `append` requests if you specify
your data as JSON (particularly when appending, for example,
list items).
## Identifying Patch Targets in a File
You can issue a GET request to `/vault/files/{path}` with an `Accept` header
of `application/vnd.olrapi.document-map+json` to get a JSON object
outlining what headings, block references, and frontmatter fields exist.

# Targeting a Sub-part of your Document
You can operate on a specific section of a note instead of the whole file by providing `Target-Type` and `Target` headers:
- Set `Target-Type` to `heading`, `block`, or `frontmatter`.
- Set `Target` to the name of the heading, block reference, or frontmatter field. If the target contains non-ASCII characters (e.g. accented letters), percent-encode the value (e.g. `H%C3%A9llo` for `Héllo`).
- For nested headings, use the `Target-Delimiter` header (default `::`) to separate levels.
You can also embed the target type and target directly in the URL path after the note identifier instead of using headers. The segment immediately following the note identifier is the target type, and the remaining segments form the target:
- `.../heading/My%20Section` is equivalent to supplying `Target-Type: heading` and `Target: My%20Section`.
- For nested headings, add additional path segments: `.../heading/My%20Section/Subsection` is equivalent to `Target: My%20Section::Subsection`.
- `.../frontmatter/fieldName` targets the `fieldName` frontmatter field.
- `.../block/abc123` targets the block with reference ID `abc123`.
When URL-embedded values are present they take priority over the corresponding headers.
When a target is specified the content is appended within that section and the full updated file content is returned with a `200` status. Without a target, the content is appended to the end of the file and a `204` status is returned.
If you need `prepend` or `replace` operations, use `PATCH` instead.
