# Content | Create library or guidebook

Create a guidebook with a customID helps to reference it when creating a Release. The attribute "customId" can be referenced by the parameter "externalGuidebookId" as explained in this article:

{% content-ref url="../releases-api/release-or-create-guidebook-release" %}
[release-or-create-guidebook-release](https://docs.guibo.travel/developers/releases-api/release-or-create-guidebook-release)
{% endcontent-ref %}

Create guidebook by using the path "guidebook", create libary by using the path "library".

* Replace <mark style="color:orange;">CCCCC</mark> with the Account ID, you can find this under Account Settings > General Settings > Account ID
* You can find the API key under Account Settings > General Settings > API Key

```javascript

curl --location -X POST 'https://services.schneidergeo.com/content/guidebook' \
